It is on the throttle body. You need to post only once. We all look at the questions and answers.

By the way. I suggest getting it fixed asap as a high idle can cause stopping issues

What size engine do you have?If you have the 3.6L it doesnt use a iac it uses the throttle plate to adjust idle.

If you cover the throttle body opening and it idles down and dies you know the problem is within the throttle body area or computer control wires etc. If it doesnt you have a big vacuum leak.

Your welcome thats what were here for.I would check for a vacuum leak before suspecting the idle air control valve.

I will check for the vacuum leak first. That seems like it would be easier to fix.
