I had weird ignition issues that were on-again, off-again in nature. I was convinced that it was the coil or a distributor issue (due to aftermarket camshaft). Nope, bad PCM! Got another one from a junkyard out of a rolled jeep shipped to me for $85. I'd try that and if it doesn't fix it, keep the PCM as an extra or sell that sucker. You'll be able to get your money back if you get a good deal to start with. If you do this, just match the code on the sticker on your stock PCM. Good luck...
