I have a 2000 TJ 4.0 auto that just started idling rough and stalling out after sitting for a few hours then attempting to start. It has a new mopar cps, coil rail, the recommended autolite plugs, new fuel pump and all the lines, battery is not even 8 months old. Once it has a little time at idle without turning off it is fine, runs strong and can restart without issue. No check engine lights.
Could this be the IAC or what else should I be looking for ?
