Persistent Issue.. P0300 and P2308 Error Codes?
Hi all -
I recently bought a used '10 Wrangler Sport 2dr with 92k miles. I got a good deal on it and I was in a bind so I took the risk. This was about 6 months ago. It ran great until a little over a month ago when I got a P0302 and P0300 error codes. I replaced the plugs and wires with some help from a few friends, and it cleared the codes and ran great. About 10 days later, it began running really rough and for some reason the #2 cylinder spark plug that I just replaced was arcing and had to be replaced again by a used plug we had on hand. Jeep began running smoothly again. So over the weekend I got the P0300 and P2308 codes consistently and I do not know what the deal is. I do not smell any rotten eggs and I have replaced the plugs, wires, and even the coil pack. I am running out of extra money to throw at the jeep.. It runs really rough and it loses power while driving. I have to pull over to turn it off and sit for a second, then crank it and it may or may not run fine until I get home. The P0300 is a multiple or random cylinder misfire and the P2308 is a bad ionization? Any body else have these issues?

HAVE YOU GOTTEN THIS FIGURED OUT? I had this now and my 2012 had to be towed home, was ticking like crazy, and now is incapacitated. I am replacing every part that the codes show, but your situation is EXACTLY, to mine.
