Stalling the engine is a common problem in cars and other vehicles. It occurs when the engine suddenly stops running, usually due to a lack of fuel or air. The term 'FLOOD' is used to describe this situation, as it is similar to flooding a room with water. Flooding the engine can be caused by a variety of issues, such as a clogged fuel filter, a faulty spark plug, or a dirty air filter. In order to prevent stalling, it is important to regularly maintain and service the vehicle.
