2000 3500 Open - Engine Sync Switch (7.4 MPI's) - BIG_D - 06-01-2026
I am having trouble with the Engine SYNC switch on the dash. When switch is activated, I slowly move the Port throttle forward (as I was told by my mechanic) and it simply increases the RPM of the motor. This just started this year! Last season the Sync switch worked flawlessly. Only difference, I put in an Electronic Control Module that connects to my Garmin Units- would that change anything within the interface?
