    Some misfires were caused by problems with the heads. There is an extended warranty on the head. How many miles are on it? You may want to talk with a dealer.

    Welcome to Allpar. Diagnosis first. Ignition, fuel or mechanical?
    The Pentastar 3.6L did have some head issues on a limited number of engines. FCA has an extended warranty of 150K miles if this is the problem.
    Usually the head failure would set a P0302 fault code (#2 cyl misfire), but it could set others as well. Sometimes a valvetrain ticking noise was also a symptom.
