    Number 2 cylinder misfire

    2013 Wrangler Unlimited Sport
    3.6L


    Jeep runs run rough and backfires.
    Number 2 cylinder misfire code that I can not get rid of.
    Changed the number 2 coil.
    Changed all 6 spark plugs.
    Did not help. Possibly made worse.
    Swapped number 2 and number 4 fuel injectors with no change.
    Tested power to all injectors and all coils. Everything has power.

    What brand and part number plugs? It makes a difference.
    Have you completed a compression test? Stuck valve possibly?

    Champion plugs.
    Has good compression and passes a leak down test.
