    If you haven't changed the spark plugs - do that first. If that doesn't fix it - it either has a coil pack(s) or COPs (a coil on each plug). That would be the second guess.

    I had the same problem, but # 2 misfire, check engine light on, neighbor a dealer mechanic suggested the following, pour one bottle of Red Line 60103 SI-1 Fuel System Cleaner - 15 oz into a full gas tank, drive a spell, disconnect battery a few minutes to reset ck engine soon light, which it did, took for another drive on intertstate a few miles, ran like new an still does to this date. Might be worth a try just a suggestion not a mechanic
