1990 Jeep Wrangler (YJ) Base 4 Cyl 2.5L


1990 jeep wrangler, not accelerating, engine cuts out when trying to accelerate.

My 1990 wrangler 2.5 4cyl is giving me some acceleration problems, the engine acts like it is going to stall out when trying to accelerate, let off the gas and all is well again. I have changed the coil, plug wires, plugs, distributor cap, rotor, fuel filter, o2 sensor, it starts and idles fine, timing is good, engine revs up fine when sitting. The problem seems to worsen as I shift into each higher gear.
