Was it warm out?

 

If the IAC gets warm, it can cause the vehicle to idle high. Out here in the desert it happens quite often.

 

We went wheeling with 4 XJs/MJs and 3 out of the 4 vehicles were doing the same thing you are experiencing and it was about 105F out.

 

You may try swapping out the IAC with another one and see if it solves your issue.
