The IAC valve would be located on the left side of the intake I think, on the throttle body. It looks like a motor, with a electrical plug going to it. The IAC opens as needed to allow air to pass, to set the idle. I don't think it would be your problem, but the port that it meters could be clogged. I may have some pics somewhere if needed.

Good Luck!
