The idle went high after the iac was changed and they're isn't any vacuum leak then I think I know what is wrong. There are after market iacs that have an adjustable pindle length. I think yours is too short and needs to be adjusted out.

How do you adjust?

Adjust them by turning them. I have never done it. The oems are set but I am sure if you Google it you will find it. Some of them are adjustable and others will break if you try to spin the it so please check. Everything seems to point to the iac.

Figured out the problem, turns out I installed the gasket in the IAC housing backwards. Chalk this one up to not paying attention when reassembling the throttle body.

Seems to be idling pretty good around 1000 hopefully it will settle around 800 after I drive it some more.

Thanks again for all the help, I really have been enjoying working on the jeep myself rather than bringing into a mechanic.

Glad to hear it. Do the battery reset.
