Misfiring at high speeds
Is it an actual MOPAR crank sensor? Where did you buy it and what did you pay for it? There is no lack of sub-par quality crank sensors for sale.
You could put in your old one as a test as that one gave you only intermittent symptoms. If your XJ starts with your old crank sensor, then the new sensor you had put is is DOA.

With my old sensor back in it will idle at 1000 rpms for a bit, misfire a bunch and then die. Also my interior lights do not work anymore when I try to turn them on. I'm convinced my Cherokee is possessed at this point.
The new Mopar crank sensor fixed the issue. Jeep starts up and runs fine but my interior lights still don't work. Not on the dash or anything and all the fuses are good.
Thanks for the help guys!
