Yj Cylinders misfiring under loadhi

Hi guys! I just bought this yj from the original owner. It's a 92 4cylinder 68k original. Driving down the highway, or the city occasionally, it just cuts out for a split second and comes back. It tends to correlate between me pressing on the gas. Once it starts it will continue until I ease off the pedal. I think it tends to happen as the car gets warm. Here's the thing. The guy before me replaced the crankshaft sensor, plugs, wires, cap, rotor, and the coil. I just replaced the tips and the computer. The computer was because it was having trouble starting like I have read in numerous threads on this site. Those problems have been solved. Truck drives absolutely awesome minus this hesitation or misfire under load. It starts right up idles fine. It does seem as if its all four cylinders cutting for a split second. Truck jerks and comes right back.

This is not an Advanced Tech question. Post your question in the YJ forum.
