First off, describe how you diagnosed it was cylinder 8 and that it is indeed a misfire.

Thanks

He provided codes and I looked them up in the DealerConnect Service Library.
Blown 7 As Ryan said he supplied the various code descriptions as werll as i already had gotten those codes when i plugged in my tool. AS I know there may be more bad plugs or coils but was hoping to find out from someone who had a similia r problem. i am thinking it may be more costy effective if i go to thye chrysler jeep service dept and pay $125.00 and have a detailed diagnoistic and print out done and nail down to specifics just broke and really am looking at that as a last rsort. Since replacing cylinder 8 coil pack and plug it is running better but still getting a problem either another coil pack a nd or additional plugs. you have any suggestions
