Default intermitten PE

I have a 2002 5.3 in my 83 jeep. I had a computer brick on me trying to correct a vss issue. I replaced the pcm with same yr and model, but ever since then I have a intermitten PE problem. Seems I have no PE until I drive down the freeway for awhile. I can shut the truck off and start it back up and have no PE until I drive down freeway again. Occasionally that doesn't work either. No idea what's going on.
