I've had the same trouble codes for the last 2 years, p0300- Random misfire and p0306- Misfire cyl #6, Changing the plugs and coil packs did not help, The codes return.

I found a TSB 1802404 which adresses this problem and was wondering if it is a valve problem will I be covered under my 7/70 powertrain warranty.

Anyway the jeep runs great so I never bothered looking into this issue.

Its just a way the mfg tells you that they screwed up building your vehicle and you have to pay to get it fixed.
