During extensive testing, it was found that completely disabling this function led to undesirable driving conditions and safety concerns. Disabling 0-cylinder mode while coasting resulted in a notable decrease in fuel efficiency, with a loss of 2-3 MPG, as the engine continues to fuel and fire the injectors even during coasting. This fueling also creates an unsettling sensation during deceleration, as it feels like the vehicle is still accelerating slightly, despite 0% throttle input. This requires harder braking, especially in scenarios like towing or descending a long grade, leading to undesirable driving conditions.
