IAC information? (having an idle problem)
 

Could someone with a shop manual scan any pages that have information on the IAC (idle air control) module? It sits on the bottom of the throttle body and has a hose that connects to it from the resonator box. I'm having a high-idle problem that I've been trying to troubleshoot. I believe I've narrowed the problem to a faulty IAC module, but I need more information than what a hayes auto repair book offers.

I'll be outside swaping the IAC module with one from a throttle body I picked up at a parts yard. I want to see if this might fix it.

Thanks in advance.
