So, i have a 1991 Jeep YJ with the 4.0 engine, it's pretty good, works really well, reliable, etc.
Recently it has developed an oddyty, 2 or 3 times out of 10 with the engine running and headlights on, when I switch the lights off almost kills the engine, it almost dies and after like 2 seconds pick it up. Like I would have disconnect the coil for a second.
I cleaned all the grounds, repair (clean and restored) the rheostat, there's no weird radio wire, and still does it.
I also try running it with the rheostat disconnect before the cleanup and it didn't die, but maybe it was just for the times I try it.
Any help?
