2004 Town and Country Missing on cyl 3

Discussion in 'General Motoring' started by Everett Cotton, Jan 23, 2007.

  1. I have a 2004 3.3 Town and Country with just under 36000 miles. My
    wife came in tonight with the engine lite lit. I read the code and it
    was PO 303 cylinder 3 misfiring. I know that it could be a plug, plug
    wire or something to do with the ignition. Maby fuel system??. Wonder
    what the most likely problem would be. Any help would be appricated.

    Thanks in advance

    I had the same problem with my 2004 3.8 Town and Country.(65k miles)
    Replaced the plugs and wires w/ bosch Plus2 platnium plugs and bosck wire.
    Big difference...now engine is really smooth.

    It could be anything. An injector, plug wire, plug, coil, etc. You could
    shotgun it but IIRC correctly there is a TSB on this issue with 04's.
    Perhaps Glen Beasly can chip in here. Whatever you do ignore the claims of
    all the fancy plugs and wires promising miracles. Stay with oem overall

    "Replaced the plugs and wires w/ bosch Plus2 platnium plugs"

    Wrong plugs. For the 3.8 Chrysler and Champion provide three options. The
    dual platinum, a fine wire dual platinum or the fine wire Iridium (also a
    platinum design). The Bosch is merely a single platinum dispite the "2"
    designation and will wear out very fast in half of the cylinders into which
    it is installed. This is more than mere theory. The basic dual plat from
    Champion is currently the OEM plug. If if runs fine and the milage stays up
    don't pull the Bosch plugs, just note this for the future.

    There is a TSB that addresses such a problem. Replacing plugs and wires and
    possibly reflashing the PCM.

  6. Took the Van to the Chrysler Dealer and they replaced the plugs and
    spark plug wiring. Runs smooth again. Thanks for the good replys.
