Engine Performance problem
1995 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 183000 miles
I cannot figure out this compression problem with my Jeep. It acts as though it will miss one to half the cylenders from time to time. It doesn't go away while accelerating but it's easier to drive at higher speeds. I've replaced the spark plugs (and made sure they were properly gapped), spark plug wires, fuel filter, fuel pump, distributor cap, fuel pressure regulator, and even cleaned out the injection system with 3M 3part fuel injection cleaning kit. I'm almost to the point of taking it to a mechanic but I thought I would try here first. Can you help me out?
