I have a 1994 FLD120 with a 12.7. The cruise is kinda funky on it. I turn the switch to on and the other switch doesn't do anything. If I flip it down to decelerat then really fast to accelerate the rpms will start climbing until I let off the swith then falls back to idle. Will never set. Any help appreciated.
