How does the cruise control hold its speed?
Cruise control does not hold its speed: If the driver sets the cruise control, it is supposed to hold the linkage through vacuum pressure contained inside the servo (or control unit). When the tank is damaged and is unable to support the servo, it increases vacuum pressure and the throttle linkage will slowly reduce.
