This only happens occasionally and does not seem to be related to engine temperature. However it does seem to happen more often in cooler weather.

IAC valve inop,vacuum leak around intake,

i own a repair shop,and a bad throttle position sensor will cause this to happen,and also a sticking linkage will do it too,but the throttle position sensor is usually the cause of this,,you can take it by any auto zone for a free scan to see whats causing this to happen,and they can tell you in a few minutes exactly what it is,and there good at doing diagnostic work also,,this is the best way to do this,i wouldn't buy one part for it until i knew for sure what it was,,electrical parts are expensive,,and cannot be returned once put on,,so be sure before you buy anything,,good luck i hope this help,s..have a good x-mas.

Throttle position sensor.I had a camaro that done the same thing.If you are running rough and have black smoke,it could be the temp sending unit.
