2002 Jeep GC revs up on startup

You need to clean the throttle body and Idle control motor. Oil and dirt
build up on the throttle blades is normal for a port fuel injected engine.
It is easy to remove and clean with an old tooth brush. While you are
cleaning it have the battery disconnected to force the pcm to reset its
learned memory.

it's a little higher than i would like to see you might clean the throttle
body and if that helps great! but if it doesn't you might want to get a new
iac motor thats idle air control motor
