The service manual listed possible causes as damaged or loose vacuum hoses to the evaporative emissions components and I couldn't find anything myself.

Scan tool may help find intermittent backfiringI have a 2002 Dodge Dakota pickup with a 3.9-liter V6 engine. The problem is that the truck backfires for a short period of time when the engine is cold. The engine starts up okay and runs fine for about two blocks.

Metallic noise could be faulty starter motorSometimes when I start my 1992 Pontiac Bonneville there is a metallic noise that occurs just as the engine starts up. It doesn't happen all the time, but when it does, the noise goes away shortly after the engine starts.

Burning E85 still costs motorist more moneyRecently, I was watching the news and there was a segment on the rising gasoline prices. During this segment, they interviewed a motorist filling his car with E85. The TV anchor correctly explained that some vehicles are built to run on E85, but gave the viewers the impression this motorist was actually saving money by filling with E85 and that's not true. Here was a motorist filling with E85 ($2.79/gallon), priced just $0.20 cheaper than gasoline ($2.99/gallon). But what the TV anchor didn't explain is that there is a substantial loss in fuel economy when burning E85. So, there really isn't a savings.

They said it would take a whole day to remove the old evaporator and another day to install the new one, at a cost of about $2,500. I was wondering if that seems a bit steep. Please advise.

Reader knows more than mechanicI'm having trouble with my '93 Chevrolet Beretta. When I accelerate, there is a jerking feeling. It doesn't happen all the time, but it is noticeable when you first begin to press the accelerator pedal. My mechanic noticed it, too and he thinks it's something to do with the brakes. I don't think it's the brakes and I told my mechanic it seems more like gas, gas filter or dirty fuel injectors.

Electrical problem causing A/C malfunctionI'm an 85-year old widow and know nothing about cars. I have a 1998 Ford Escort that has a problem with the air conditioner. Last summer my A/C went out and when I took it in for service it was working perfectly. A couple of days later it went out again.

What could cause this to happen?

Do stored trouble codes erase automatically?I have a question regarding my 2002 Dodge Durango with 38,000 miles. My "Check Engine" light came on and after about ten restarts it went back off. Does the Diagnostic Trouble Code (DTC) stay in the computer, or will it be erased automatically? I brought my Durango into the dealer and they said that the DTC gets erased and therefore they couldn't find a problem. Is that true?

Excessive fee to fix Jeep's heaterI have a 2000 Jeep Grand Cherokee. It has dual heat and air conditioning controls. At the end of last winter the vents on the passenger side started blowing cold air all the time. The driver's side works fine. The dealer said that the motor that operates the air exchange door had spun out. The price to fix this was just under $1,000 because they said they had to take out the entire dashboard. Is there someway I can just wedge this door open? I'm not going to spend that much on a vehicle that is 6 years if I can help it.

Extra 5 percent on repair bill has consumer seeing redI have a question about an additional 5 percent charge (for cleaning supplies) that is added to my repair bill at a couple of the repair shops I frequent. I was wondering if this fee is common at other repair shops. When I inquired about the charge I got a vague answer. It seems similar to a company tax that they put on your bill for themselves. If it is for cleaning supplies, maybe I could bring them a roll of paper towels when I bring my car in for service. The 5-percent adds up quickly. What do you think?

Spark plug replacement goes awryMy son was replacing the spark plugs in his 1991 Toyota Corolla and he accidentally stripped the threads in one of the cylinders. A handy neighbor came by to help and he couldn't get the spark plug reinstalled after many attempts. He said that the spark plug hole would need to be rethreaded and that would require removing the cylinder head because pieces of metal might fall into the cylinder during the rethreading process and damage the engine once it starts running. Do you know of any methods to fix the spark plug hole without removing the cylinder head?

Front brakes wear out too fastThe front brakes on my 1992 Ford Taurus only last about 5,000 to 10,000 miles. In contrast, I get about three times more service out of the front brakes on my 1994 Ford Crown Victoria. My technician told me not to be concerned as front-wheel drive cars are harder on their front brakes than rear-wheel drive cars.

No-start condition eludes several mechanicsMy 2000 GMC Sierra 1500 truck has performed very well except when the temperature drops below freezing. When that happens, the truck will not start. We've taken it back to the dealer several times and they haven't been able to find anything wrong. Most recently, we took it to a local mechanic who was also unable to determine the cause. Our mechanic even towed it to another mechanic and the problem is still not resolved.

Bet on a Porsche if you want to win the raceWhat is the highest-performance car you drive on the street and still win races with on a track? I've got a bet that racing has become so sophisticated such a car hasn't existed for decades

Who should install my remote starter?My son was recently shopping at a local department store and he purchased one of those remote starter systems for his car. It came with a video on how to install it along with a website and 800-number for technical support. He's installed his own car stereo and he's pretty good with his hands, but I wonder if the installation might be better left to a professional. What do you think?

Bad switch could prevent high beams from workingI'm having trouble with the high beam headlights on my 2002 Chevrolet Impala. When I turn the high beams on, they'll stay on for a few seconds and the lights will turn off. If I turn the high beams off, the headlights will come on again. What do you think is wrong?
