My 97tj 4.0 sometimes stumbles and back fires. Then cleans up and runs fine they rest of the day. I have random miss fire codes but that is it. I was told it could be the computor can anyone confirm this or how can I Ck the computer?
I would check the ground and all the wires going to the the comp b4 replacing the comp its self, have way more cases of it being just a wire n not the comp especially if its a rig that goes offroad
