CM871 poor power and fuel econ

[Grounded Pilot]

Yes, replaced #1 and 4 injectors but that was after the actuators were replaced the first time. The #4 injector was bad enough that it was causing the motor to continue running after the fuel was cut off. I can’t speak for previous drivers, but I don’t let them wash the motor/electronics. I’ll look at the link. I’ve taken the plugs apart and cleaned and dried them out and made the connections as good as I can but that didn’t change anything. I did find that the cab 50amp breaker was pretty corroded. Going to change that out and wire brush the cable ends good.
