When the vehicle speed slows, the fuel supply will come on again. Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine's rpm are critically high, the fuel supply to the engine is shut off. When the engine speed slows, the fuel supply will come on again. This helps prevent damage to the engine. Tachometer (Analog Cluster Only) This gage indicates the engine speed in revolutions per minute (rpm).
