Cylinder one contribution showing -6 with a bad miss. Truck has had intermittent miss for last few weeks. Trucks studded bpd oil cooler new drivers bank injectors and bpd water pump and running a healthy custom tune. Temps and such are monitored religiously. Had intermittent miss for several weeks (stiction o believe) now its just a dead miss. Took it by friends shop since my scan tool wasnt working and he said contribution seemed too high for bad #I injector. He thought might be bigger issue. Fuel pressure is over 65psi running no bubbles in the bowl cranking. Pretty sure it's an injector just want someone else to tell me this dead miss is an injector because I'm going to be taking time off my paying jobs to fix this and that side is a pita to get too. Was gonna run bore scope down that side. Any other ideas before I tear into it. ???
