2006 TJ 4.0 misfire issues

[Cajun001]

hopefully this will be the final post on this particular issue.
Since changing out Crankshaft Position sensor (Mopar) and CLEANING OUT THE DIRT IN THE WIRE HARNESS and now full engaging the sensor and wire harness my Jeep appears to be back, have put 50 miles on it and is running great. Thanks for all the Technical knowledge and encouragement during my troubleshooting. I will make a list of items to replace and the OPDA is on the top, what other items can be problem items after 100,000 miles?
Thanks again for the help and warm welcome to the TJ group!

PS. I do have a very small oil leak, is there a particular location that the jeep is know to have these small leaks?

I would start a new thread or find another one regarding what to address > 100K, but I'd look at replacing the entire cooling system and replacing brake fluid. Inspect all suspension bushings, etc.

Oil leaks occur at the valve cover gasket and the rear main seal mostly, although mine also leaked from the oil pan gasket too. The threads you're looking for can be found in here: https://wranglertjforum.com/forums/tj-resources.121/
