It can be severl things but the two that I would suggest is the cps and clogged cat.
iac can cause it if it is not working and tps can effect the timing if it is going out.

sorry about that,cps is crankshaft position sensor,located top left of bellhousing,it is looking at the tone ring on the flexplate,it can get dirty and cause this,it is one of the most important sensors on the jeep,cat is catalytic converter,iac is idle air controller,tps is throttle position sensor,both located on the throttle body.
