The problem is when I start the car when it is already warmed up.
Leading evidence: 'when i start the car' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'when i start the car' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Clean thottle body, pull the maf' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I'll clean the thottle body, pull the MAF and clean it, and check if I have an idle control valve.

Have you checked or cleaned the throttle body yet?

Oh, and can you clear a CEL by disconnecting the battery for a minute?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 01 C2 cab with 63K miles idles at 650 RPM. The needle points just over the 3rd hash mark. The idle is actually pretty smooth. The problem is when I start the car when it is already warmed up. Here's the scenerio: I'll stop to pick up something at a store after driving around for an hour or more. I try to start up the car again, the engine catches immediately, revs up really high and as the revs come down, the engine stalls. All this happens in about 3 seconds.
Any ideas? I know my idle is a bit low too....
My guess...
Have you checked or cleaned the throttle body yet?
Also, you might have the idle control valve in your 01 (not sure), if so, check that as well to see if that needs cleaning.
does the MAF have anything to do with this? - I am no expert on electrical things, thats for sure. it sounds like something not giving the correct signal to control the idle. -
is the A/C on?
could be low battery voltage -
someone should pop in with some suggestions shortly - hang tough!
OK,
I am going to work on this tommorow. I'll get some throttle body cleaner and some electrical spray cleaner. I'll clean the thottle body, pull the MAF and clean it, and check if I have an idle control valve. I still don't know if the 01 has it...
I have never touched the engine on this car, so I'm hoping it goes well.

I have a similar issue.
2001 C4 w/90k miles. Started around 80-85k. When already warmed up, the car starts, but then immediately wants to turn off. It hasn't stalled yet, but I suppose it's inevitable.
It happens frequently enough to cause serious concern, but not consistently enough to reproduce on demand for a mechanic.
