That is where I go and from there diagnose that to see if it is working properly.\n. \nBest I can do for you now............... (MORE)

Why does 2003 Chevy Malibu check engine light keep coming on I thought it was the fuel cap so you tightened it and it worked but it comes back on and goes off and comes back on?
It can take up to a week for the check engine light to go off after you have tightened the fuel cap. If it is still not going off it could be a sign of a bigger problem. Take it to a place and they can hook it up to a computer and diagnose the problem.
How many miles will pass before check engine light recycles and goes off due to the fuel cap not being on properly on a 2004 mercury mountaineer?
Mileage is not what determines when the trouble code is cleared. There specific criteria that has to be met before the light will turn off. For example some codes require that the car go's thru a specific number of drive cycles. A drive cycle would be the engine starts cold then fully warms up. Some… codes require this to happen two times or more. Other codes require you drive the car at a specific speed for a certain length of time. Its very technical and specific. Most manufatures answer is this for a loose gas cap: Conditions for Clearing the MIL/DTC. â¢ The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.. â¢ A current DTC, Last Test Failed, clears when the diagnostic runs and passes.. The typical gas cap code should clear after you fill up and use about 1/3 tank of gas. But like the above says 3 ignition cycles so go drive your car and let it cool down three times. Dave (MORE)

No, I think they started using simple and not so great computercontrolled systems in 1987.. ************************************************* Rule of thumb is if it is fuel injected it has a PCM or ECU (samething) a carbuerator, no. There are exceptions but you won't go farwrong with that. The last… American built car with a factorycarbuerator was some Oldsmobile , Buick , Cadillacand Jeep in 1990. Ford Crown Victoria Police Interceptors until1991. Cadillac Seville had EFI as early as 1975 (MORE)

Can the fuel pump cause the service engine light to come on and the car become sluggish in a 1992 Chevy Caprice?
If the fuel pressure is too low that might cause the service engine light to come on and , since there would not be enough fuel pressure, might also cause a sluggish response. That could be caused by a clogged fuel filter also.
Push the right side of the fuel-tank cover (which is round) and it pops open.
Diesel fuel is ignited by a combination of heat and compression. The heat is caused by the very high compression in the cylinder. The fuel also has to be very finely atomised to be able to burn.
