Default 2003 jeep cherokee revving up??

Ok fellas....I need some help with a sick one. I just fixed my 89 cooling system and now my daughters jeep is acting up. It's a 2003 with the v6. It revs to about 3000 rpm when started and in park. Continues to act up driving and at stop lights.....Sensor, vacumm leak, computer glitch or easy fix?? Relp...has about 100,000 miles or so on it right now with just routine maint.

It's a 4.0 straight 6.Check the IAC and TPS.Those are usually the culprit.
