Disconnect the O2 sensor and see if the problem goes away! If it does the problem is with the O2 sensor or its wiring/connector
I had the same problem 3 months ago. Turned out I had the O2 sensor and the TPS sensors both attached to the wiring harness backwards (C connected to A instead of A connected to A). They were both fairly new parts too. But mine was behaving badly all the time and yours comes and go. If it comes and goes it is more likely electrical!!!!!!! and not a camshaft lobe problem.
If it still runs fine in reverse then forget the cam lobe problem the dealer suggested.
Could it be the transmission, TCU or a TCU wiring problem????
Have you pulled and cleaned all the ground wires yet?!!!!!!
Could be a loose, dirty ground wire for sure!!!! Jeeps are notorious for ground problems. Search here in this forum for gound problem stories, where the ground connections are and how to fix them.
Also check the serpentine belt, the tight turn voltage drop / head light dimming sounds like a loose or greasy belt.
