Just got a 6.0 Powerstroke that was running on 5 cylinders back to a full roar in my driveway this afternoon.
After tracing a dead injector to a bad connection at the FICM harness, I cleaned the pins with some electrical cleaner and a toothbrush, and now it idles smooth as glass, so what's your go-to fix for those finicky FICM plugs?
