Does the car only die while driving or will it die it you let it sit and idle until at operating temp? i have a 94 regal GS and it would die when at operating temp intermittanly but would work fine in colder weather. found the crankshaft postion sensor to be failing when it would get warm. that is on a 3.8 liter not sure what motor you have. hope this helps. if that is the case you should be able to get that sensor for $25 to $30 dollars at your local autozone.

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!.

When I first start up and drive my V-6 95 mustang, its drives smooth for till it gets a little warm,, then when I come to a stop light, it begins to Idel real rough, LIKE a spark plug is bad, it does not...


hi, this is a common problem and the main problem is going to be with the oxygen sensor ( also called lambda sensor) replacing this should solve your problem.

When you first start your car you will find that it will run ok as the oxygen sensor only starts working when it reaches a certain temperature so this is most likely the cause of your problem. It can be expensive to get the part but it will solve your problem.

Let me know how you gwt on or if you need further assistance ok

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.
