put a new one in and the old was shot, 130,000 on it Took it apart and it was a mess Frozen and no way it would work properly, plastic was deteriorating BAD inside it. If your idle is a little rough probably your IAC is no good or partially working It is basically a little electric motor with a screw that moves in and out.

 

That's what I figured was wrong.

 

how much is one of these so called IAC and how hard is it to change it?

 

and several guys had used ones, but I would buy new. Easy to change out.

 

I have a brand new one for sale. $50 Email me mikey97z@reanimator.org if interested!

 

the grease gets like gum or whatever they put in there, mine was a mess and no way it could of worked properly, if you get a new one, take the old one apart and look at it, you will be suprised, mine had 130,000 on it and it was shot.
