Those are the classic symptoms of a plugged up Idle Air Controler Motor. It controlls the air into the throttlebody at idle. It is the left (passenger) side of the throttlebody, and removing and cleaning the carbon from the pintle and throttlebody should help.

I always have that problem after I've drained my battery. Make sure you've got 12v at the battery when the jeep is off and approx 14v when it's running.

Try the fuel filter...might be a case of bad gas...not that I'm having the same issues caused by bad gas clogging my filter...now to find out if it took my pump also.

its just odd because sundevilkid said something about the battery and having the slow crank/low volts at idle..wondering if changed the battery or alternator would cure it..well scratch that one cause i know the alternator works because the volts went up when i would rev the engine..anyone thinking the battery may be the culprit??

hmmm that's interesting.. I've noticed that my jeep is cranking slowly since it's gotten cold.. not sure how old my battery is because it dosn't have any markings on it. it's just a plain black battery. OEM maybe? on a 92'? hard to believe. I'll look into a new one, maybe that will help my cold start hesitation also.
