Engine misses out when warms up

I have a 1993 Jeep Grand Cherokee, with a 5.2 automatic. (It has 245,000 miles) I had to replace the pcm, as it completely stopped running. I have also replaced the coil, plugs, map sensor, crankshaft sensor, rotor and dis. cap. It runs fine until the engine warms up to 185 degrees, then it misses out and cannot get a full throttle engine rev-up. I am not getting any error codes from my pcm. This is driving me crazy.
