95 j30 runs good when cold but "missing" after abut 15mins

When I start my J up in the morning it runs great. After about 15 mins the idle revs up high after comming to a complete stop. I then have to kick the gas pedal and the idle comes back down to normal.

Any other suggestions???

idle air control, clean that up, maybe it will help, and check your vacuum lines (if they are all connected and tight)
