have you checked all your vacuum lines?

Try covering the Throttle body with your hand, if the car still runs, and doesnt shut off immeadiatly, 10 to 1 you have a vaccum leak...

Bleed the coolant... air pockets can cause the IAC to adjust the idel up and down. Also if you have a Fast idle vavle under the throttole body.. take the side cap off and see if the plastic screw is all the way in.

Make sure also the IAC is not showing a check engine light for.
