How to clean the IAC valve
if your idle is off or you have a whining noise this may be all you need to do instead of buying a new IAC valve try cleaning it.
remove the IAC valve from the intake manifold by removing the 2 10mm bolts, and disconecting the plug
remove the black cap on the side of the valve to allow it to drain and dry properly, this is just a vent cap
you can use sensor cleaner or electrical cleaner. spray in the 2 holes on the side let it drain and spray some more, there is usually alot of carbon build up in there it may take several sprays
let it dry compleatly before re-installing

This is interesting... I have a roaming idle a minute or two after startup as well as a whining noise during acceleration...
I'll try this tomorrow. Work today, FML.

For me i was not very lucky. I had to buy a new IAC but it wasnt but 32.00 i got a discount on it when i worked at oreillys. Although imo i did try to clean it first but it kept cutting off or acting like it wanted to cut off.

Re: How to clean the IAC valve
I think what he's saying is that there is already a well established how-to thread on this topic.
And it's already accumulated alot of questions and answers.

Re: How to clean the IAC valve
can the IAC valve be damaged easily kind of like the MAF sensor?

Re: How to clean the IAC valve
I cleaned mine, and the throttle body, and MAF. My MPG went to shit. I don't think that cleaning it messed them up, I think it uncovered another issue that I have yet to solve. I dropped 2 MPG doing it.

Re: How to clean the IAC valve
Does this run metal to metal or do I need to grab a new gasket before removing it for cleaning? 3.0 V6, vin U. Thanks.
