Ok, here's a super cheap or free idea:
With a piece of ~18g wire add a ground wire directly from o2 sensor to chassis- make sure it's clean metal you attach to. Strip 2-3 inches of the wire and wrap it around the slightly backed out o2 sensor and retighten it. Same for chassis side.
Now on the subject of o2's, there's a chance this needs to be replaced.. If you've refreshed all grounds (check Cruiser54's Renix tips) and replaced sensors then move to fuel delivery. Check the filter, if there's debris, check the tank. Sorry I I'm repeating things you already did- I'm on the app :/
I replaced the entire sending unit in the tank about 2 years ago with a "Airtex" unit. It came with new everything, bracket, screen, pump all complete to drop in. I cleaned the tank out spotless before I reinstalled.
The reason I had to replace my original pump was because the gas ate through the rubber line after the screen that goes into the pump and it had debris of rubber all in the tank.

O2 shouldn't cause bucking that bad, but if it's original it's always worth a look.
I'd suspect that marvelous Airtex pump...

Got my buddy a factory fog light switch from the jy out of, if I remember correctly, a 94 Cherokee. Does anyone know the wiring diagram for it? We're wiring in aftermarket fogs with a relay.

Black is ground. Either green wire could be 12 volts and the other the accessory, it will just depend on how the switch is orientated. Get a multimeter and play with it on the battery.

What would stroking the 4.0 do to the driving feel? Would the longer stroke reduce the response initially? Also I have an exhaust on, if I did stroke it would it make my car unbearably loud?

[Cool beans, that was super helpful
all I know is that involves a different crankshaft with a longer stroke. I dont know why I'm getting sarcastic answers when I've seen question with much more stupidity answered on this forum.

Not sarcasm, bud. Salad is very knowledgeable, but he needs to know how far to break down the info. You may not know what a stroker is, or you may be an engine builder. We get all kinds here, and we don't know you yet.

I do all of the fixes on my JEEP besides engine and drive train stuff. I'm only 18 but I'm trying to learn and it irritates me when people condescend so sorry for that.

Anybody have any issues with the transfer case handle vibrating? Mine vibrates back and forth when I'm coming to a stop and it's really annoying. Is there a way to tighten it up or something?
