Lazy cruise control
My cruise control has trouble maintaining speed. If I set it to 70 on flat ground, it will hold at 68 then drop to 65 going up a hill. If I don't help the gas pedal down with my foot, the cruise control doesn't have enough pull to get the pedal down far enough and my speed will just drop forever until I notice and give it help. I'm sure the components are just worn down from years of use. Could it be a vacuum leak somewhere? Should I replace the diaphragm that pulls on the throttle cable or is something else busted?
