Hello I have a 2005 Grand Caravan and the other day the check engine light came in. It was during a time when the engine was acting like it had bad gas. Had the same issue in 1997 in Kodiak Ak. I checked the codes and got a code of 0304. Can anybody point me in the right direction to figure out what this code is. I have not taken it in yet because of being in a remote location of Juneau, Ak. I work Mon-Fri just like they do.

 

P0304 is cylinder 4 misfire. There is a TSB out on this concern and it involves replacing the plugs, wires and reprogramming the PCM.
