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. At my wits end, someone please help.

Thanks

Oh Yes! I had this problem about 10 years ago on 1993 Dodge Dakota. Both Dodge and Jeep are made by Mopar. I had the exact syptoms and did the same as you. I came to the conclusion that the bearings for the distributer were shot. Changed bearing going into engine block and i had no more BAD MISS. I KNOW THIS WILL WORK FOR YOU.GOOD LUCK
