Hey new to the forums here. I have a question for anyone who can help me out. I have a 1994 Cherokee 4.0 ho. It's been acting up lately so I'm trying to problem solve here. I can drive it for awhile then when I park it for like 15min it doesn't wanna start. We replaced distributor cap n rotor, spark plugs n wires, fuse relays, thermostat, n swapped ecu's with my brothers gf jeep. Something is getting hot afterwards I just dnt kno what? Any ideas?
