I have a 2008 dodge charger rt awd. We keep getting a misfire code on cylinder #4. We
have changed the plugs twice, #4 coil pack, fuel injector, cleaned the throttle body,
replaced 2 mds solenoids, computer update,replaced valve seal, replaced erg valve,
dealer ran 2 bottles of cleaner through intake and the light is still on. Compression tested
good. The dealer is taking me and my wallet for a ride. I need some professional help
please.
