Not a direct fit out of the box.
Shouldnt be listed as a fit for a 1999 jeep tj 4.0 liter. IAC valve came with the wrong size o-ring which was too big, I tried using the original o-ring but it was too small so it would not seal properly. I sent pictures of both old and new IAC vavle for refrence. I couldnt find the proper o-ring to seal and sit the IAC properly.

Idle air control fix
I had a bad idle air control valve and I replaced it with a new one and it runs like new now. The part was reasonably priced and the shipping was fast. I would definitely recommend this company to any of my friends. Thanks John

Air idle control valve.
This was the correct part and seems to have fixed the problem. And the part was less than half price than from local auto supply stores.
