PO304 Any Advice?,,,,,

[eckerd_explorer]

so this code has been popping up for a while now. i've replaced the egr valve, the DPFE, and the plug. i'm still geting a pending PO304 code(#4 misfire) i've searched the site and saw that the # wire rests on an egr line causing a little too much heat which may lead to the misfire. could that be the prob? any help would be great. thanks.

Yes, it's probably the wire. I'd replace it, or at least check it with an ohmmeter. (Normal resistance is 6K-12K ohms per foot). Also check/clean the #4 coil pack terminal.
