High Idle
 

my car idles at 1200 - 1400 rpm but only when you drive it. you can start it cold and it idles fine. if it was sucking air other than the throttle body would this happen?

Hey Mike.

You have a Vacuum leak somewere! With the car idleing go around it with a propane tourch "not lit" lol when the propane gets sucked in the car will increase its idle.
