The engine in my max has been revving to almost 2000 RPM when cold starting. And, the idle RPM varies between 600 and 800 RPM after warming up. I cleaned the T-body but that did not help so it's time to clean the IACV.

I bought a Chilton's book hoping to get some info and pictures, but it had very little useful info. So, does anyone have pictures they could post/e-mail? Also, does the IACV have a gasket? Anything I need to be aware of? Any help/tips would be appreciated.

Thanks in advance for your support.

 

I cleaned the throttle body and IACV a couple of days ago. The car starts much better now and revs at 1500 cold. The IACV is held in by two screws, one on either side. Remove the 3 electrical connectors for access, take out the two screws and the valve will come off. There is no gasket. Haynes warns you not to soak it in solvent so I cleaned it with a rag as much as possible and then used some throttle boby cleaner on the valve tip. I also cleaned the hole in the throttle body that the valve fits into.

Hope this helps.

 

Thanks! Just the kind of info. I was hoping for. In fact, I think I'll go out to the garage right now and have at it.

Thanks again.
