If you can wait a few days, order a Dorman from Amazon for $58.

Already taken care of. Amazon was 58 and free shipping, and it just so happened that I had about 40 or so dollars credit with them so the net total came out to $15.xx, and I did the free 5-8 day shipping because my Jeep is daily driver as it's a 4 cyl manual and already has 250k miles on it, might as well put the rest of my mileage needs on it until it dies.

Well my suspicions were correct. The new FPDM showed up, I installed it with no problems, but the misfires continue. I removed every spark-plug. They all looked normal except #4 and #8 were a little darker for some reason. I'm just going to replace all spark plugs, then start on my COP's. To heck with this hit and miss beating a dead horse and what-not. Once all 8 plugs and COP's are new, if misfires continue, I'll look elsewhere. Afterall, the COP's have 150k miles on them and they're 10 years old. I'm thinking their integrity is starting to slip and maybe they're making weak sparks and that could be the reason for the darker spark plugs on the back. It would also explain why the engine revs smoothly in Park, but once under load, bucks like a rodeo bull. I changed the fuel filter a couple years ago, but I'll probably do it again, I guess it just takes one batch of bad gas to clog one up.
