Hello! I just recently purchased a 2015 jku with 130,000 miles. I bought it knowing the engine light was on thinking I could fix it with a few parts. Its a good clean ride completely stock. It’s throwing codes p0300 and p0302.. (misfire in cylinder 2)
Thing is it runs and sounds just fine. If the light wasn’t on I would’ve even suspect anything to be wrong.
First we replaced the coil after noticing the plugs were recently replaced, cleared the codes and the light popped on the next day.
I ordered mopar brand plugs and replaced all 6 plugs, cleared the codes and the light popped back on within 20 minutes.
We found that whoever had the Jeep before had 3 different brand of plugs in it. Which tells me they couldn’t figure out the issue either and just traded it in.
Has anyone had a similar issue that figured it out?
