Part # and why does my jeep run and drive fine when I disconnected the IAC?

 

This is what I bought. http://www.summitracing.com/parts/sm...FURk7AodSUkAtQ

 

TPS part # 4874371AC

The symptoms listed are just possible. Sometimes they're weird and idle fine even with the IAC unplugged. Did you try actually driving it with the IAC out? You definitely should have noticed a difference.

 

No the IAC was still in the throttle body, I just unplugged the wire

 

would still have the same effect. You're disabling the IAC so engine should respond. Take it fora drive with it unplugged and see how she reacts.

 

It drove the same when I unplugged the wire to the IAC

 

Weird. Now I'm a little befuddled. I'll do some digging and see what I can find.

 

If you can, unplug the IAC on your jeep tomorrow and see what happens.

 

Just went out and did it. Ran like absolute crap. Wanted to stall out unless I was giving it gas. Now I gotta go clear an engine code. Thankfully I have a scanner.

 

So I should definitely get a new IAC

 

Just pull the one in there (unplug it and then it's two t20 torx bolts to actually remove the valve itself) and clean it up with some throttle body cleaner. It may just be real dirty. Can of cleaner cost less than a new IAC.

 

I've cleaned the throttle body and IAC already. Maybe I damaged the IAC somehow when I cleaned it

 

Or it's just bad. Mopar IAC part # 4874373AB

 

Anyway to test it?

 

Not really. Only real test is to install one you know is good and compare the results.
