What could cause the car to idle roughly when not moving but in gear? When its still but in gear ( Ie: Redlight ), it vibrates rather roughly, when its in park its fine, and when its moving its fine. It also on occasion has sharp drops in rpms ( around the 300 mark ) over and over again, typically when running the AC. Anyone have any idea what could be causing this?

Do you have an Auto? Manual? Have you unhooked the battery recently?

I ask because when you unhook the battery the ECU resets. When you hook it back up you need to let it sit and go through the re-learn process, or it will drive like crap. I did this a while back and went through a tank of gas in a day. not fun.
