E30 m20 misfire, checked everything please help
Hey guys I've been having a issue with my 86 e30 325e turbo. The car generated a misfire.so yesterday I pulled the plugs and cyl. 5 plug was completely black and the others were fine. I checked the spark plug wire and cleaned the spark plug up. I checked fuel pressure and its good. I checked injectors and they're all clicking the same one doesn't sound different than the others. I don't know what else to check. The plugs are brand new.it seems like its not getting spark all the time or the injector is stuck open.
