Is it a 6 cylinder or a V8? If it's a 6 cylinder, then yes, it very well could be the IAC needs cleaning.
You can see a thread on how to do that here:
How to clean your IAC (Idle Air Controller) valve
While that thread covers the 4.0 in our TJs, I know it's probably identical for the Grand Cherokees as well.
Lastly, is there a check engine light on?
