Hey guys new to the forum and I have a few questions. I have an 06 Dodge Charger RT police package with about 130k miles on the ODO. Ive been having a misfire issues and was wondering if you guys have the knowledge and advice to maybe help me isolate the issue. I've ran the code and P0308 pops up every time I erase it and it keeps popping up. I've changed all plugs and coilpack on cyl 8 and is still misfiring. It has an extremely rough idle and low thud coming from the right side exhaust. Any ideas or information on this matter?
