Have you checked your tps? It's a cheap part that could be the culprit, if spitting and sputtering is what I am thinking of. Also o2 sensors. It sounds like a electrical fuel to air sensor problem, since you say it's off and on. Try plugging up a buddies and seen of it makes the difference. Start cheap and work your way up is my motto.

Sorry missed where you said you changed the tps. Also if you leave your jeep out in the rain a lot. Your clockspring In the steering wheel shares the ground as the tps. Easy way to bypass it is to unplug your horn relay and see if it was your tps ground. But also check your o2 sensors
