When you start the car after it is warm, 50 percent of the time it has a rough idle. But when its cold the car is fine. When it does have a rough idle, once you put it in drive or start moving its fine, traffic lights and everything it idles fine.
Do you
have the same problem?

Check for vacuum leaks and check the IAC (idle air control valve)

Is there a different type of IAC on this car, becasue I just replaced one on my truck, and know what that one looked like, but I can not find one on this car, I know that it will be on the throttle body, but did they start using something different or different looking?
