Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry for the long wait and that you have this problem my name is Gary
all other times the truck is fine only at a stop this will happen with your foot off the gas pedal ?
ok i was just being sure
when these will only stall at a stop at idle with the AC on the issue is usually a dirty throttle body where the computer can not properly adjust the idle correctly to compensate when the AC is on or the computer programming needs to be updated in the computer
its best to clean the throttle body and if it still does this have the computer reprogrammed and the crank sensor relearned and the idle with the scan tool
