HELP! Get Bubba Rubb out from under my hood!

WHHOOOOOO!!

Thats the sound it makes!
It seems Bubba Rubb has made it under my hood.

What is that thing called that makes this anoying noise? I know where it is. On 4.0 OHV drivers side of intake. With the little black cap on it.

I need to replace it.

IAC or Idle air control valve.

THANK YOU!

No w I can just clean it right? Instead of replacing it?

I sprayed from O2 safe carb cleaner in mine. The whistling comes back about every 4k miles tho. I guess you could just clean it every oil change.

I was reading some post this morning about how to clean it, I sure if you did a search you could find how to clean it, it sounded pretty easy and by the replies people had it seems to work. Good luck!

I believe the IAC is getting clogged because of a bad PCV valve. Try replacing it and see if this solves your problem. The EGR will send back gunky air if you have a bad PCV valve and this will clog the IAC.

I think this is correct, but I could be completely wrong. I know my PCV valve needs to be replaced and my IAC is getting very dirty quickly.

hmmmmm..

well the pvc is the original and it does have 103k on motor! I just replace PVC and clean IAC!

I had mine replaced under warranty over a year ago and WHOOOO just recently came back. I took the POS off and sprayed throttle body cleaner liberally inside and out of the IAS and it cured it for now. If you had to pay for a new IAS, I'd say your better off just cleaning it annually. Those things cost like $45 or something I think.

No, they cost ~$100 at Ford, $60 delivered from FPN.
