In order to avoid paying a diagnostic fee at a service facility I would proceed to the nearest auto supply store that has a scan tool that you can use. If you are not sure how to use the tool ask the counter person to help you hook it up and retrieve the code from the vehicle computer. This code helps pinpoint what needs to be repaired in order to get that light to turn off. If you get the code(s) I will be happy to provide you with more information.

1999 Denali rough idel and driving


You should have 2 02 sensors in your exhaust system. The second one trips the ligt if your emmissions are too high abd it monitors the condition and efficiency of the cat converter. The 02 sensor in front of the muffler monitors the fuel adjustment for too rich or too lean. Now, on a cold start there ias a "cold start valve tha enriches your fuel like a choke. It can be the culprit because the #2 02 sensor is doing its job. The cold start valve can be chk'd to see if it is working by observing it.. It is behind the Throttle body. It should be clicking. Good luck and I hope this helped. Oh, wwhen the engine warms up, and you have clear the exhaust of excess fuel the light should go out.

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

IDEL VERY ROUGH, IT RUNS GOOD BUT IDEL BAD


If the check engine light is on, then take the car to an autoparts store and have them scan the computer for any fault codes stored. The check engine light is to alert you that the computer has noted a fault in one of the car's systems. It sounds like a problem that could be caused by a faulty idle air control valve, but getting the codes will eliminate the need for speculation and should narrow down cause of the problem. Sorry for your trouble and I hope this helped. Best wishes.

1994 Cadillac DeVille Concourse - Runs rough?


The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.
