To find the IAC follow the air intake tubes until they attach to the throttle body (it's attached to the intake manifold), then look under the air intake tubes just in front of the throttle body you will find a solenoid with a 2 wire connector on it. It has two bolts attaching it to the intake manifold.
If you have not had a problem since you ran the fuel system cleaner through it, I don't know if I would recommend cleaning or replacing it at this time.
