A co-worker of mine has an 06 durango that is throwing P0304 code. Cylinder #4 misfire. She has replaced the spark plugs and the coil for #4 but the code keeps coming back. Currently running some fuel injector cleaner through it but has not cleared the code yet. Any other ideas I can try? I know since we have replaced the coil and plugs, all that is left is fuel related just wondering if anyone else has had this code and what you did to fix it. Thanks!

 

This thread needs moved to the Gen2 section. A 2006 D is not a Gen3.

my apologies, my truck is an 05 which is a 3rd gen, so I figured an 06...well nevermind, my bad.

 

No prob jk.
