I have a 1990 Cherokee limited with a really unique problem. After driving highway for about half an hour or on backroads or about 45 minutes it starts to chug and try to choke itself out. If I drive for a few more minutes it will choke and stall wen I stop at a light or sign.
As far as I know I've done all the work needed to stop this, including plugs, wires, ran injector cleaner and seafoam multiple times, even fixed a vacum leak on the throttle body. I'm out of ideas and could use some help.

Hey man. Your problem is not actually that unique. I have the same issue. Do a search for grounding issues and find out how to clean your ground points. These years (RENIX) have a history of grounding problems. I still have to do mine but that should fix the problem. Keep me in the loop.

Ok thanks I'll try. I've had 3 people look at it, 2 of them actual mechanics, and none of them had any clue. Smh

Any luck fixing this?

Try the ignition coil - touch it after it starts acting up. See if its really hot. It might be overheating for some reason and acting up.
