2006 dodge caravan 3.3L engine code question

[jordan12]

I have a 2006 dodge caravan 3.3L with 237,000 miles on it. I noticed that the engine light came on. I used a code machine and it came up with P0306 and P0304. Not sure what these actually are referring too.. Cant seem to notice any difference in idling or power or anything. Any ideas on where to start for resolution?

That's a lot of miles for a 2006. How's it been working?
Those codes pertain to misfires (#4 & #6 cylinders). When did you last change the spark plugs and spark plug wires? #4 and #6 are at the front, on the Driver's side. Hit any big puddles lately?
Haynes Manual 2003 thru 2006 has the codes and is a worthwhile investment for some repair work.
This site also has the codes: http://www.allpar.com/fix/computer-codes.html

The engine runs well. Very smooth, and has plenty of power. I almost probably go over board on maintenance. But it has rewarded me..However, the wires were replaced at 130000 or so and I havent messed with them since. I think I am going to go with the wire replacement and see how that gooes.


The plugs were recent. But I didnt think about doing the wires, since they looked ok..So Ill fix that and hope this fixes it.
