Idle air control valve replacement

I was going to replace my idle air control valve today but I had to take the mount off to get to it. I realized it was because the bottom bolt was rounded. I haven’t got it off yet but I also cracked the gasket on the mount. Is there a more exact name for it other than the idle air control valve mount or where I can get one so I can replace that as well?

Mopar no longer makes the part, but there are plenty of other brands who make replacements, such as this one:

What about a place to get the mount from as well because I’m still not able to get the bolt of?

I can guarantee the only place you'll find that is on eBay, or http://car-part.com (it searches all the auto wrecking yards within X miles of your zip codes).

That's not something you're going to find unless it's on a vehicle someone is parting out (hence the http://car-part.com link).

If you have to make your own, this may help instead of trying to trace it. I found this on another Jeep forum.

I have also seen people use RTV allowing it plenty of dry time.

Can you grab the bolt head with a pair or vice grips? Needle nose vise grips might work better. Then just replace the bolt with the same size from a hardware store.

Unfortunately I did try that and there was no movement out of it at all. I just did what jerry recommended and just cleaned it and put it back together. I’ll probably just grab it off a part out Jeep one day.

Hopefully you also cleaned the orifice in the throttle body the IAC's plunger fits into. That has to be just as clean as the IAC is to prevent the same problems a dirty IAC causes. The easiest way to clean it is to spray TB cleaner into the throttle body while the engine is idling. Revving the engine during this will bypass the IAC and the orifice so the cleaner will bypass both and not clean them.

Jerry I know you recommend leaving it in place which I believe would work if you maintain a regular cleaning schedule starting with a clean TB.

When I cleaned mine I’m not so sure your method would’ve done a good enough job. I sprayed the day lights out of all the disassembled parts and I still needed a significant amount of elbow grease to get them clean.

Now that mines clean I will be following your recommendation.

That damn gasket took the most time of it all. Cut mine from NAPA stock gasket material.
