2004 Town and Country Missing on cyl 3

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
better.

 

"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.

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