A fuel injector is a small valve within your vehicle's engine that opens and closes to allow fuel into the combustion chamber. Fuel injectors are responsible for spraying fuel into your vehicle's engine. They disperse fuel toward the intake valves, creating a fine mist of fuel particles. The fuel injector must always be working properly to ensure the engine runs smoothly.
