Can someone tell me what, if anything, the little black round **** on the side of the IAC does?

 

What is the IAC?

 

There's no **** on mine... Can you post a pic?

Sorry, I can't figure out how to post a picture on here, so here is the link to advance auto.

I believe it is a vent

 

That would make sense. It spins but doesn't apparently do anything and I was reading in someones post where someone mentioned adjusting the IAC so i started wondering if that was some type of adjuster.
Thanks.

 

The IAC is 100% computer controlled. You can clean it when it's dirty and replace it when it gets flaky, but that's about it.

http://fordfuelinjection.com/?p=39 has a very good explanation on what the IAB does.

 

prrcatenary,

The IAC is the Idle Air Control solenoid and valve assembly on the driver's side of the throttle body and mprice is right, there is no adjustment for it.
