FYI... on a chevrolet throttle body, there is a process for resetting the Idle Air Control motor. I don't recall exactly what it is, but there should also be a process for the Jeep throttle body.
It is something like unplugging the IAC and threading the plunger all the way in. Then you hook it back up and turn the ignition on (without cranking)to let it thread the plunger back to where it needs to be against the throttle body.
The gap between the plunger and throttle body controls the air into the TBI therefore controlling the idle.
