Revs high in neutral while moving

[acesn8ights]

My 2001 mustang v6 started revving to a little over 3000 rpm when I push in the clutch or shift into neutral while I'm moving. After I come to a complete stop and sit for about 5 secs the rpms lower but are still higher than normal (about 1300 compared to 600 before). It its at normal rpm when in gear and the clutch isnt pushed in.

I took out my IAC and cleaned it with throttle body cleaner which seemed to help for about 3 days. It then did it again so I went and ordered a new one. One my way to pick it up the next day it stopped doing it again. I had already bought the new IAC so I installed it. Well that was two days ago and now its back.

Is it possible that this is some other issue and the temporary fixes were just a coincidence. I was thinking possibly the MAF or TPS.

Thanks for the help!

How to trouble shoot IAC idle problems

Check first for vacuum leaks. Next check the fuses.

Have you adjusted the throttle body set screw in an attempt to resolve this?

No I havent touched the throttle body set screw. I've been busy but Im going to try a few things today to see if I can fix this.

Thanks.

Its probably worth noting that the CEL is NOT on.

What are the results of the tests called for in the post? What about the visual inspection? Fuses?
