RUNNING ROUGH AND WONT PASS INSPECTION

1990 Jeep YJ

Engine Performance problem
1990 Jeep YJ 4 cyl Four Wheel Drive Manual 200200 miles

I have replaced the speed positioning sensor and the O2 sensors, new plugs, wires, distributer, and rotor. It is in time with the timing light but still runs rough like it is missing on one of the cylinders. I am stumped and about ready to sell it! HELP
