I am a recent owner to a 2003 Monte SS, I have owned the car for about two years now. And have been having problems with the car in the winter months. When it gets cold outside the car seems to stick at a higher RPM's even when first started and when it has been running for a while. At an idle it doesn't want to drop below 1200 RPM's after it is completely warmed up. One day it even stuck at 3,000 RPM's which of course makes it just about impossible to drive!! I have had a mechanic look at it and hook it up to his computer, the only thing that the computer read was that the thermostat wasn't opening fully, so they replaced that and it seemed to be working fine for a few days and now its back to being the way it was! and now the check engine light came on. I have had a few people tell me they think it may be the throttle body position sensor has gone bad, i know the mechanic looked and did some tests to see if there was a leak near and around the throttle body and they found nothing!

The throttle body positioning sensor sounds like the problem. I'd look in to that.
