Good Day,

That could be caused by the TPS(throttle position sensor), or MAP(manifold absolute pressure sensor), is yout check engine light on? If it is it probably a sensor. If not it could timing, a vaccuum leak, or other possibilty's. What size motor? The 4.3L or 5.7L?

Let me know I can try to assist further.

Chevrolet Caviler 2.4 - 2000 Stalls at idle (stopped) once car is fully heated up.


Check coolant temp sensor. These fail often and cause all kinds of mystery problems. This unit acts much like a choke on old carb engines and can fail in different ways. Most common (I think) they fail such that the ECU thinks the engine is cold when it has begun to warm and thus the ECU delivers too long a pulse to the injectors so that the engine runs way too rich. I think it is also possible for the sensor to fail at any point between cold and warm such that the fuel mix is wrong except for the particular temp at which the sensor is stuck. Also O2 sensor has some fuel "trim" input.

Chevroleete caviler - car wants to stall or does stall when idling after warmed up - not always. When in drive at idle speeds once in a while cars revs will jump up to 2.5 - then have to restart


Did you clean the idle air control motor, when you cleaned the throttle. Also check for vacuum leaks. The PCM controls the IAC motor. If it to dirty it can stick. Can cause a surge and stall.

4 cyl Engine starts and idles ok...give it throttle and it dies


I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?

Car petrol engine revolution surges.


Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Stalls and wont idle when cold


many automobiles behave that way on a cold start, so you don't have to worry about it. just continue to rev the engine until it is warm!
