Since it does come back to initial setting, probably not.My 06 1800 drops 4 mph before it catches up to the set speed when I set the cruise..
Does anyone know how to adjust that out..
Most cruise controls are set with a tolerance range, so it doesn't constantly hunt back and forth trying to maintain set speed.
When the control unit see's the speed out of tolerance, it adjusts accordingly. You can adjust the cable until you're blue in the face, but the control unit will dictate set point.
