    Is my PCM bad?

    Got a little technical question. My 2002 tj 4.0 5 spd with 221000+ miles would occasionally stutter some but otherwise ran great. The check engine light was on and I got P1391. I swapped the cam sensor, no change. Swapped the crank sensor, let it idle 10 minutes and drove it across the yard...
