Matt, Kinda hiliarious and a total long shot but you are basically driving my jeep with the same exact problem and I"ve thrown the sink at it as well. Chasing my tail for an electrical issue I firmly believe. Curious if you ever found the root issue. Thanks! I know it is a year later but why not
Jeep 2012 108K miles 6 Speed Man
Missfiring Random Cylinders 1,3,5
Checked injectors, Coil, new plugs, new bank 1 cam sensor. Compression is good 150lbs cat is not plugged, tested with a gauge. Got all new 02 sensors too.
None of the above seem to move the problem. Checking harnesses but i'm guessing your issue is the exact same rubbing spot somewhere in it.
Thanks
Jason
