"Dr. Gizmo"

By Phil Arendt

Getting The A/C Ready For Summer Heat

Question 1

The air conditioning in my 2004 Chrysler Concord is not working.  I took the car to my local repair shop where a technician performed tests.  He did not find any trouble codes in the air conditioning computer.  He said the system has plenty of Freon and that it should work.  He does not know what is causing the problem, but he does know that there is nothing wrong with the compressor.  He says the compressor engages when he forces to turn on.  At this point he will charge by the hour for his diagnostic work.  He is not sure how long it will take to find the cause of the trouble.

I have to get this fixed before hot weather returns.  Do you have any suggestions?  A.N., email

Answer 1

This may be a case where aftermarket diagnostic equipment software is not sophisticated enough to find the trouble.  If you have a long and trusting relationship with your technician ask him to consider voltage tests of the temperature sensors.  These sensors react to temperature by changing voltage in the system and turn on the compressor.  He might find one of them is not functioning within specifications.  If so, replacement of the faulty sensor should return normal function system.

If you are not comfortable with your present repair shop consider taking the vehicle to a dealership where odds are greater manufacture specific diagnostic equipment will perform system tests that will find the cause of the trouble.

Power Steering Affected By Debris

Question 2

The power steering in my work truck intermittently does not work.  It is a 2007 Ford E150 with a 4.6 engine and 57,000 miles.  I checked the fluid level.  It is fine.  The belt is tight and in good condition.

 

The power steering can be working just fine when suddenly it becomes stiff and I hear a buzzing sound from the pump.  I can drive for days without any problem.  Then for whatever reason I can be driving along without any problem and the trouble surfaces.

Do you think this is caused by a faulty pump or is there a valve or something sticking?  Would flushing the system fix the problem?  G.N., email

Answer 2

This is unusual.  Generally, a power steering pump works fine or it doesn’t work at all.  The symptoms you describe point toward restricted flow of hydraulic fluid.  It is possible something is blocking the flow of hydraulic fluid to the pump.  Perhaps there is a foreign object floating in the reservoir that occasionally blocks fluid to the pump.  If this is the case suctioning the fluid or removing the reservoir for cleaning may remove the object that causes the trouble.

Flushing the system might cure the trouble but I’m more confident removing the reservoir for examination and cleaning is the correct approach to this unusual condition.  Who knows what happened but maybe something dropped into the reservoir when someone checked the fluid level or topped it off.  Ask your favorite technician to consider this theory when you take the truck to a shop.

Technical Service Bulletin To The Rescue

Question 3

The check engine light is on in my 2003 Nissan Altima.  It has a 6-cylinder engine and 75,000 miles.  Sometimes when I start the car it runs fine and the light is off on my dash.  Sometimes when I start the car it starts fine but as I am driving the light turns on and the engine idles too fast or the idle slows and the engine stalls. 

I took the car to my local repair shop.  They found two codes.  One was PO507 and the other was U1000.  A mechanic checked for air leaks in the engine and tested a throttle control.  He said there are no air leaks and the throttle control passed tests and is functioning normally.  He says there is something wrong in the wiring or there may be a faulty module that causes all the trouble.  He says it may take a day or more to find the trouble. 

I’ve never had a car with such a problem.  Does this make sense to you?  Do you have any suggestions?  T.K., email

Answer 3

Thanks for providing the trouble codes.  PO507 is an indication of possible air leaks or faults in the throttle control actuator or related circuit.  Trouble code U1000 relates to a problem in the circuit in the controller area network or CAN.  Your car is computer controlled with computers and computer modules placed just about everywhere a design engineer can place a module but don’t despair. 

A check of technical service bulletins found a lengthy bulletin that addresses a CAN communications circuit problem.  This may be the key in finding the fault in your car.  If your technician has not already done so, ask him to look up bulletin NTB06-009a.  The procedures outlined in it may be just what he needs to troubleshoot the condition.  It deals with cleaning and securing several ground connections in the circuit that are in the dash and engine compartment.  It is a big job and will likely take several hours to accomplish the task.  If his shop is busy he may need to divert attention to other customers while he is working on your vehicle so plan to leave the car in his hands for more than a day.

Code Signals Troubled Transmission

Question 4

When I drive more than 30 minutes the check engine light turns on in my 2003 Cadillac DeVille.  When the light turns on I do not notice anything wrong or unusual about the car.  It starts and runs fine.

I confided in a friend who is knowledgeable about cars.  He says it is likely one of the oxygen sensors is failing.  He told me to take the car to an auto parts store to have codes retrieved from the system.  I did and the partsman found code 741.  He said there is something wrong in the transmission.  My friend told me to take the car to a transmission shop to have the problem repaired. 

The transmission seems to be working fine.  Will continuing to drive the vehicle cause harm to the transmission?  N.B., email

Answer 4

Automatic transmissions are very complex machines that can suffer severe damage from the slightest malfunction.  Consider taking the vehicle to a repair shop as a precaution.

Diagnostic trouble code PO741 retrieved by your partsman does indeed relate to transmission trouble.   It refers to a failure of the torque converter clutch.  The code means there could be a problem in the torque converter or problems in the circuits, solenoids and valves in the transmission that control the torque converter clutch.

If your vehicle has traveled over 100,000 miles it is possible it is time for an overhaul but repair to circuits, solenoids and valves may not require removal of the transmission from the vehicle.  If it is determined the torque converter needs replacement the transmission does need to be removed to access the part.  Let’s hope faulty wiring is the cause of the condition as this is the least intrusive repair.

Hummer H2 Not Humming Along

Question 5

At times the 6.0-liter engine in my 2005 Hummer H2 will not crank when I turn the ignition.  Also, sometimes the ignition key binds and sticks when I turn it to start.  These two problems can occur at the same time or independently.  When the engine does not crank I turn off the ignition and turn it back on and the engine usually cranks and starts within three turns of the key.  If the ignition key binds I can’t turn it to start the engine.  I might have to remove the key and stick it back in two or three times before the ignition turns to start.

What causes these problems?  R.S., email

Answer 5

It appears there are two different problems.  To repair the ignition key problem, removing, cleaning and lubricating the lock cylinder might be all that is necessary.  Over recent years several General Motors models have had issues with ignition lock cylinders and the cleaning procedure has cured the binding problem.  If it does not, it might be time to replace the lock cylinder or maybe the ignition switch.

As for the engine not cranking to turn over and start, this too may be a simple condition to cure.  Some Hummers had issues with the battery terminal bolts coming loose.  Check the terminal cable connections.  They might be dirty, corroded or loose.  If these conditions exist, remove the cables from the battery terminals and clean them.  Additionally, it might be necessary to replace the bolts if they have been attacked by corrosion or the threads are broken or striped.   Once the terminals on the battery and cables are free of any dirt, grime and corrosion, reinstall the cables nice and snug.

Avoiding Repair Shop, Free Repairs

Question 6

This morning I was pulling into my driveway in my 2009 Buick Enclave when the engine stalled and would not restart.  The instrument lights turn on when I turn the key to start and the engine cranks but it won’t start.  The power windows, seats and radio all work fine so I know there isn’t a problem with the battery.  Also, the gas tank is nearly full.

I checked all the fuses in the passenger and engine compartments.  All the fuses except a fuse marked ECM1 are okay.  I replaced the fuse and attempted to start the engine but it still would not start.  I checked the fuse again and it was blown.  I touched the computer in the engine compartment and it felt hot.

My vehicle has 56,000 miles and a 3.6-liter engine.  I don’t want to go to a repair shop if it is not necessary.  Do you think there is something shorting out in the engine compartment computer?  Can I purchase a computer from General Motors or auto parts store without having to go to a dealership or repair shop?  Is there something else I should look for?  N.G., email

Answer 6

Wow, you must have had a terrible experience at a repair shop not to want to have your vehicle towed to a shop.

 

Certainly there could be a short circuit in the wiring to the engine control module instead of a short within the module itself.  However, a hot module is a clue there might be trouble within the unit. 

As for purchasing a module, you can’t purchase a unit directly from General Motors but you can purchase it through one of the franchise dealer parts departments.  Additionally, you can purchase a module from an auto supply store, but I think you should reconsider your position about not taking the vehicle to a repair shop especially to a dealership.  With only 56,000 miles and a few years of use your wheels should be covered under the factory warranty.  If so, you won’t have to go through the hassle, expense and guesswork trying to determine the cause of the trouble and repairs should be free of charge. 

Give it some thought.  Call a dealer or General Motors Customer Service to discuss the matter.  You can find the phone number to GM Customer Service in your owner’s guide.  Also, your owner’s guide explains the factory warranty.  If you take your vehicle to a dealership all concerns may be resolved to your satisfaction and your car will be repaired without scraping a knuckle or spending a dime.

Chrysler Group Launches Vital Second Phase of PHEV Minivan Project

• Three plug-in hybrid-electric vehicles (PHEVs) delivered to the Sacramento Municipal Utility District (SMUD) as part of demonstration project by Chrysler Group LLC
• Twenty-five plug-in hybrid Chrysler Town & Country minivans now in service
• Vehicles developed in partnership with U.S. Department of Energy
• PHEVs will be used to evaluate city drive cycles, thermal and charging performance, fuel economy and real-world performance

April 25, 2012 , Auburn Hills, Mich. - The data-collection phase of Chrysler Group LLC’s plug-in hybrid minivan project begins in earnest with the completion of the demonstration fleet’s deployment.

Three plug-in hybrid-electric Chrysler Town & Country minivans went into service today with the Sacramento Municipal Utility District (SMUD), bringing to 25 the total number of such vehicles on American roads.

“The focus now shifts from engineering design and development of this unique technology, to real-world testing and evaluation,” said Abdullah Bazzi, senior manager of Chrysler Group’s advanced hybrid vehicle project.

The plug-in hybrids will be subjected to “temperature extremes and variations of drive cycles,” Bazzi said, adding resulting data will shed light on customer acceptance of the technology and its impact on the grid.

Other deployments are in Arizona, North Carolina and Michigan.

Two additional plug-in hybrid minivans will be retained by Chrysler Group engineers. One of those vehicles will be subject to a short-duration test by Argonne National Laboratory.

The two-year project stems from Chrysler Group’s partnership with the U.S. Department of Energy (DOE). The DOE has invested $10 million to further the research.

Each plug-in hybrid Town & Country is equipped with an E85-compatible 3.6L Pentastar engine mated to a front-wheel-drive, two-mode hybrid transmission.

It also is powered by a liquid-cooled 12.1 KWhr lithium-ion battery that affords a total output of 290 horsepower and a range of 700-miles. Charge times are two-to-four hours at 220 volts with a “Level 2” charge cord unit, and eight-to-15 hours at 110 volts with a “Level 1” charge unit.

The vehicle’s hybrid system does not require charging.

A fleet of plug-in hybrid Ram pickups also is being evaluated as part of a wider project.

TORRANCE, Calif., April 25, 2012 – Scion today announced full details for its 2013 FR-S compact rear-wheel drive sports car.  The high-performance coupe is the fifth model to join the Scion family and will go on sale in June.
 

“The FR-S will definitely be Scion’s halo car,” said Scion Vice President Jack Hollis.  “While the brand has been iconic with the xB, adrenalized by the tC, and groundbreaking with the new iQ, the addition of the FR-S expands the brand into a new dimension of driving performance.”

Authentic Sports Car at an Affordable Price

The FR-S provides the automotive landscape with an authentic sports car at an affordable price, with a MSRP of $24,200 when equipped with a six-speed manual transmission, and $25,300 when equipped with a six-speed automatic transmission that features paddle shifters and Dynamic Rev Management technology.
 

“Scion’s goal was to create an affordable sports car that true driving enthusiasts could enjoy,” Hollis said.  “We accomplished that with a starting price under $25,000, which is a total home run for buyers!  Add in Scion’s complimentary Scion Service Boost, our dealers’ no-haggle no-hassle Pure Price, and Scion’s network of about 1,000 dealers, and the FR-S is a grand slam.”          

“Pure Balance”

The FR-S, which stands for Front-engine, Rear-wheel drive, Sport; is Scion’s definition of an authentic rear-wheel-drive sports car with exceptionally balanced performance and handling, compelling style, flexible utility and surprising fuel efficiency.

           

The FR-S is a true “scion,” born into a lengthy history of Toyota performance cars and motorsports. During planning and development, it was most inspired by the AE86 generation of the Corolla, better known as the Hachi-Roku, meaning “8-6” in Japanese. The AE86 was a front-engine, rear-wheel-drive coupe that was lightweight and well balanced, making it a solid choice for driving enthusiasts.

 

Inspired by the AE86, the FR-S is designed around the core goal of achieving “Pure Balance,” which begins with the strategic use of the world’s only flat boxer engine in a front-engine, rear-wheel drive configuration.  The engine’s compact size and flat shape allow it to be mounted mid-ship and extremely low, giving the car a dynamically favorable front-to-rear weight ratio of 53:47 and a low center of gravity comparable to some exotic supercars.

The FR-S’s 2.0-liter, naturally aspirated four-cylinder engine is the result of a joint development between Toyota and Subaru.  The partnership begins by combining Subaru’s newly developed, horizontally opposed engine and Toyota’s cutting-edge D-4S injection system,which incorporates both direct and port injection for each cylinder, one injecting fuel directly into the combustion chamber, the other a port injector located above the intake valves.  Adopted from the Lexus IS F, D-4S injection is a new technology for the Scion family.
 

The D-4S system uses the direct injectors at all engine speeds. Both the direct and port injectors are used at certain engine speeds and under certain engine loads to help fill out mid-range torque. The D-4S is also a key technology that reduces vehicle emissions. FR-S heads utilize dual variable valve timing, making adjustments to the intake- and exhaust-cam timing to help optimize power, torque, and fuel mileage.  The D-4S system, partnered with a high 12.5:1 compression ratio, results in an impressive 200 horsepower and 151 pound-feet of torque.
 

Despite the engine’s powerful 100-horsepower per liter, the FR-S has EPA-estimated ratings of 34 mpg on the highway when paired with the automatic transmission, and EPA-estimated 30 mpg with the manual transmission.
 

The flat-four mates with either a six-speed manual or a six-speed automatic transmission. The manual offers quick, precise shifts with a short-throw; while the automatic features aggressive up shifts and sporty rev-matched down shifts that are initiated by steering-wheel-mounted paddle shifters. The automatic features Dynamic Rev Management technology that quickly raises the engine speed to help match engine revs to gear ratios on downshifts, limiting driveline shock and adding to the visceral experience of driving the car.

 

The automatic transmission also features Sport Mode that quickens shift timing as well as throttle response. In Sport Mode, the transmission will also hold gears longer at higher revs before upshifting, making it easier to exploit the torque and horsepower in the upper reaches of the rev range.

Both transmissions have the same 4.10:1 final drive ratio. To help bring the rear-wheel-drive design to life, FR-S features a Torsen® limited-slip differential, apportioning power to the rear wheels with precision and immediacy.
 

The idea of “Pure Balance” is further realized by the FR-S’s lightweight design and compact size, a combination that allows it to be quick and nimble into and out of corners, with dynamic maneuverability and confident handling.  The coupe weighs in at an impressive 2,758 pounds when equipped with a manual transmission and 2,806 when equipped with an automatic.  The FR-S is kept to a minimum weight by utilizing an aluminum hood, a solid roof, and by featuring a trunk design instead of a hatchback.
 

The FR-S’s low weight is complimented by a dynamically tuned suspension setup consisting of MacPherson struts up front and a double wishbone system in the rear. Excellent steering feedback and input is provided by Electronic Power Steering with a sporty 13:1 steering ratio. Lightweight 17x7-inch alloy wheels and ventilated disc brakes are standard on all four corners.
 

For the sake of experienced performance driving enthusiasts, the Vehicle Stability Control (VSC) and Traction Control (TRAC) can be set in combination of five configurations.

Powerful Exterior Design

The fierce exterior of the FR-S is a solid reflection of its inner power. The profile, inspired by the Toyota 2000GT, reveals a hood and roof-line that is remarkably sleek and low, giving it an aerodynamic shape that channels air cleanly over to the top. The low stance continues to exaggerate the coupe’s menacing face, which is made up of sharp lines, a wide lower intake and angular headlights that house the projector-beam halogen lamps. The aggressive front fenders protrude upward and boast the iconic ‘86’ piston emblem, which highlights the car’s AE86 heritage as well as its unique new boxer engine. The rear fascia sits low and wide, with aerodynamic lower treatments that surround the sporty dual exhaust system.  LEDs illuminate the edgy taillights, while center-mounted backup lights finish the muscular design.

The FR-S will be available in seven colors including Raven, Asphalt, Hot Lava, Argento, Ultramarine, Firestorm and Whiteout.

 

Performance-focused Interior

The FR-S’s interior includes a 2+2 seating configuration that is designed with both form and function in mind.  The comfortable yet assertive front seats feature deep bolsters and are mounted extremely low, while the rear seat folds down flat, creating flexible space.  It will also come standard with unique FR-S badged floor mats.

The large center-mounted tachometer is the focus of the three-gauge cluster and features a programmable shift-indicator, which has a small but intense indicator that lights up when redline is reached.  The driver can set the warning to go off in 100-rpm increments, starting at 2,000 rpm.  A chime can be programmed to sound when redline is approached. Speed is monitored by both digital and analog gauges.
 

The FR-S features a performance-oriented, 365-millimeter diameter, leather-trimmed steering wheel that has both tilt and telescopic adjustment.
 

The soft-skin dash top has a “flat horizon” design, influenced by the simple purity of the Toyota 2000GT dash.  At the center of the dash top is a raised rib, which functions as a “centerline” that reflects at the base of the windshield, helping a skilled performance driver intuitively find the center of the car.
 

The FR-S will come standard with an eight-speaker AM/FM/CD/USB 300-watt maximum output Pioneer™ audio system.  Standard features also include HD Radio™ technology and Bluetooth^® connectivity that allows both hands-free phone connection as well as streaming audio capability.

The FR-S will be the first Scion to offer a connected multimedia audio system called BeSpoke™, powered by Pioneer’s Zypr™.  When connected to an iPhone^®, Scion’s BeSpoke system will offer a higher level of connectivity features and personalized content like Facebook, Twitter, Internet radio, among others.

Sports Car Performance with Excellent Safety Features

FR-S comes standard with six airbags, including dual-stage advanced driver- and front-passenger airbags, front-seat-mounted airbags and side-curtain airbags.
 

Like all Scions, the FR-S features the Star Safety System that includes Traction Control (TRAC), Electronic Brake-force Distribution (EBD), Vehicle Stability Control (VSC), Brake Assist (BA), an Anti-lock Braking System (ABS), and Smart Stop Technology (SST).

 

Warranty and Complimentary Scion Service Boost

Like all Scion models, the FR-S is covered by a 3-year/36,000-mile limited warranty and a 5-year/60,000-mile powertrain warranty. The FR-S will come standard with Scion Service Boost, a complimentary plan covering normal factory-scheduled maintenance for two years or 25,000 miles, whichever comes first, and two years of 24-hour roadside assistance.

The delivery, processing and handling (DPH) fee for all Scion models is $730 and is not included in the MSRP.  DPH fee for vehicles distributed by Southeast Toyota (SET) and Gulf States Toyota (GST) may vary.

BMW Lease Protection Program

Woodcliff Lake, NJ, April 23, 2012 – BMW Financial Services has taken the next step in offering its Ultimate Lease customer a smoother, less-stressful lease-end experience – and overall simpler leasing experience – with the introduction of its BMW Lease Protection Program.  

“Our new BMW Lease Protection product , which some might refer to as extended-wear-and-tear coverage, virtually eliminates the potential out-of-pocket costs  of common repairs at lease-end , thus making the leasing experience that much more pleasurable,” explained Lisa McPherson, BMW Financial Services general manager of insurance. “This is our latest program to make leasing a BMW (or a MINI) a pleasurable experience and minimizing issues surrounding wear and tear, tire and wheel problems and minor dings and dents which may become apparent when the vehicle is returned at the end of the lease.”

BMW Lease Protection joins BMW Tire & Wheel Protection, BMW Paintless Dent Repair and BMW Windshield Protection to provide coverage for everyday mishaps. These same programs are offered to MINI customers.

“One of the reasons people lease cars is for a virtually worry-free driving experience, one which enables them to enjoy their vehicles for the life of the lease and then either walk away or move into their next BMW or MINI,” explained McPherson. “We understand this and are continually upgrading the BMW Ultimate Lease to make the experience that much more pleasurable and rewarding for the BMW Financial Services customer.

“Taking the costly surprises out of the lease experience by providing BMW-level protection is the obvious way to do just that.”

The BMW Lease Protection Program, which must be purchased at time of new-vehicle delivery, covers up to $3,750 in billed excess wear and use charges at turn in (not during the life of the lease). Items covered by the program include:

- Dents and dings
- Tires
- Wheels
- Upholstery, rips, tears
- Glass
- Headlamps (including Xenon), fog lamps, tail-lamp assemblies
- Bumpers, step bumpers, surrounding trim
- Navigation/display screen
- Factory entertainment system
- Convertible tops
- Carpets
- Mufflers and tail pipes
- Rubber door seals
- Mirrors, mirror covers and housing
- Name-plate badges and hood ornaments
- Moldings, trim, metal and chrome
- Missing parts (up to $300 per occurrence)

The process for determining excess wear and use occurs at the lease-end inspection, generally performed at the BMW Center. There an inspector reviews the vehicle, noting if there are any items in need of attention. If so, the information is presented to the customer (who will receive a comprehensive lease-end inspection report) and the claim is submitted to BMW Financial Services directly by the dealer – the customer does not have to do anything.

Northwest Herald Dr. Gizmo column Dated April 13, 2012

"Dr. Gizmo"

By Phil Arendt

Trans Stuck in Third Gear

Question 1

Two months ago, the transmission failed in my 2007 Mazda 6.  It has 64,000 miles and a 2.3-liter engine.  When the transmission failed the car barely moved and needed a tow.  A shop installed a remanufactured transmission.

Two weeks ago, I was driving when the engine revved up and the transmission would not shift from one gear to another.  I returned to the repair shop where they test drove the car and checked it for trouble codes.  The mechanic found two codes - PO734 and PO841.  He erased them and drove the car.  The transmission shifted normally.  I drove the car and it shifted fine.

Last week, while I was on a road trip the transmission shifted from first to second and third gears but it stuck in third gear and would not upshift.  I was about 600 miles away from home when it happened.  I took the car to an independent repair shop where a mechanic tested the transmission.  He found the same codes as the shop back home.  He erased the codes and the transmission returned to normal.

I continued my return trip without any trouble until I was I about 10 miles from home.  The transmission stuck in third gear once again so I drove home unloaded the car and went to my repair shop.  They found the same trouble codes as before.  Now they are not sure what is causing the trouble.  Do you? M., email

Answer 1

There are several possible causes for the two codes.  The troubles include faulty wiring, a failed oil pressure switch, failed vehicle speed sensor, failed control module, sticking valves or slipping clutches.  If a technician does not find trouble in the wiring, sensors or module he should consider contacting the company that remanufactured the unit and have them send another transmission.  The work should be covered under warranty.

All-Wheel-Drive Makes Buzzing Sound 

Question 2

I hear a buzzing sound coming from beneath the floor of my 2007 Ford Edge with all-wheel-drive, automatic transmission and 3.5-liter engine.  The faster I drive the louder the buzzing is.  It sounds like it is coming from the transmission, but the transmission shifts fine. 

I had the fluid flushed in the transmission, but the noise is still there.  What else could be the cause?  L.K., email

Answer 2

There could be a failure of a bearing in the all-wheel-drive power transfer unit or possibly in the transmission.  The power transfer unit (PTU) delivers engine power to the rear wheels.  It is connected to the transmission so a noise from either unit could lead to misdiagnosis as to which unit has a fault.

Since the transmission is functioning as designed, more than likely the trouble is in the PTU.  If so, it is likely that the unit needs replacement with a remanufactured assembly.

Convertible Fails To Function

Question 3

I own a 2008 Chrysler Sebring convertible.  The top does not go down.  It has a 2.7-liter engine, automatic transmission and 62,000 miles.  As you can see by the miles I like to drive the car, but I like it more when the top goes down.

Recently, when I hit the switch to lower the top the windows went down but the top did not.  Also, a convertible top warning light turned on in the dash.  After this I discovered that the trunk will not open from the key remote or the dash button. 

In an attempt to resolve the trouble I checked all of the fuses, but they look fine.  Is there anything else I should look for? V.R., email

Answer 3

There have been cases of hydraulic fluid leaks from the motor that powers the top.  If you are a seasoned do-it-yourselfer, check it for leaks.  If it is leaking fluid try to determine why and correct the condition.

If there are no leaks, consider asking an experienced technician to test the system.  The technician that is awarded the work needs to have test equipment that can communicate with the convertible top control module.  Since some aftermarket test equipment will not communicate with the module, your chosen technician will have success if he has Chrysler specific test equipment such as a DRB or Witech.

Once trouble codes are retrieved from the module he should not have any trouble determining the cause of the failure.

Backfire Raises Comments From Neighbors 

Question 4

My 1996 Chevrolet Tahoe with 142,000 miles and a 5.7-liter engine backfires when I start.  Once it is running it runs fine.  Since the condition began a few months ago the engine has been tuned with new spark plug wires, distributor cap, rotor, new spark plugs and air filter.  Also, the crankshaft sensor, fuel pump and starter have been replaced.  One mechanic also thought the valves were sticking so he did some tests and examined the valves after removing the valve covers.  The valves seem to be working fine.

The truck is in great condition.  It has never let me down.  Whatever the problem is I will have repaired.  I have to get this fixed.  My neighbors mentioned they hear the backfire when I leave for work early in the morning.  Now my mechanic thinks there is something wrong in the distributor that is causing the backfire.  Does this seem right to you?  L.S.E., email

Answer 4

Watch out!  Neighbors with pitchforks and torches may come to your house.  When your truck backfires they probably duck for cover.  This condition needs a quick repair before the exhaust system blows right off the vehicle. 

Your technician may be on the right track.  Considering vehicle mileage, it is possible bushings on the distributor shaft or the drive gear is suffering from excessive wear.  If this is true, wear can cause the engine to backfire.  Replacing the distributor is the likely approach to a lasting repair.  

Once this is repaired, peace and love will return to your neighborhood.

Cracked Wiring Insulation Hinders Engine Starts

Question 5

Two days ago without any warning my 2004 Nissan Altima started right away, but then it died.  It has a 2.4-liter engine.  When it starts it runs for a few seconds and stalls.  Pressing on the gas pedal does not help.

I removed the spark plugs and found they are wet with fuel. 

I went to a parts store to buy spark plugs.  An employee suggested that the trouble could be caused by a bad crankshaft or camshaft sensor so I installed new spark plugs and sensors.  This did not fix the trouble.

While I was replacing the spark plugs I found some cracked wiring to the ignition coils.  The insulation is cracked, but the wires inside are not.  A friend told me to replace the entire wiring harness.

Do you think this has anything to do with the problem?  If I cut the wires and repair them with waterproof connectors do you think this will fix the trouble?  Should I replace the harness?  P.D., email

Answer 5

It is doubtful you will be able to purchase a brand new harness.  They are scarce and expensive.  Also, replacing it may not fix the trouble.

Try to repair the wires.  It is the least expensive task.  It may or may not fix the trouble, but at least you won’t spend a ton of money.

Let’s hope it does the trick.  If not it is time to ask an experienced technician to troubleshoot the condition.

Check Engine Light Signals Misfire

Question 6

For the past year the check engine light has been intermittently flashing in my 2006 Subaru Forester.  When the light first began to flash I took the car to my local shop where a mechanic did some tests but he could not find anything wrong.  He suggested that I wait until the light turned on steadily. 

Presently, the light is not on steadily, but it is coming on more frequently.  Also, when the light turns on I feel the engine hesitate a little.  When the light turns off the engine runs fine, but I’m fearful the car will leave me stranded.  Now that the light turns on frequently do you think my mechanic will find the trouble?  Do know what causes the trouble?  S.W., email

Answer 6

Your description of the performance of the engine indicates it is misfiring.  If so, malfunction trouble codes should set in the engine control module.  Tests by an experienced technician should determine the cause.  It is possible a spark plug needs replacement.

Sometimes troubles such as this are caused by oil leaks at the spark plugs.  If this is the cause, it may be necessary to replace the valve covers on the engine.  This is not major surgery, but such a problem does raise repair cost.
