In my last video I made a trip to pick up a 392 Hemi Swap for my 2010 Jeep JKU. On the trip, my 2020 Jeep Gladiator started stumbling, running rough, and then finally displayed a flashing check engine light. The code was P0302, which means misfire on cylinder 2. The flashing engine light means its an active full misfire.
In this video we pull the JT into the garage to figure out what went wrong!
The 3.6 engines in these and the JL have had some misfire issues in the past. Alot of people reached out saying they had issues with cylinder heads, auto start battery issues, and even issues with the ECM causing misfires.
Recently, i added a set of RIPP high performance coil packs. They did make a noticeable difference, and looked to be made very well. My first thing to look at would be these coil packs..

Hopefully this video helps out someone, its important to remember what all goes into modifying our Jeeps.

We will see how long the other coil packs last for. Hopefully this will not be a continued issue, but we will see.

Thanks for watching, and i cant wait to start up the JK Hemi swap, which also means we need to finish up the LJ LS swap.
