will not idle at initial startup

Asked by Dec 05, 2014 at 05:56 PM about the 2004 Cadillac DeVille Sedan FWD

Question type: Maintenance & Repair

Rough idle at startup car will shut off unless you press gas pedal, runs great on road and
still has a little rough engine when stopped at a traffic light. Could it be a choke sensor or
other sensor. Check engine is now on !

1 Answer


check for vac leaks, but you should probably clean your throttle body. idle air control is also suspect. have the computer scanned for the codes that the light is telling you about. autozone will scan it for free.
