Fuel injectors are computer controlled spray nozzles that deliver fuel to your engine in precisely controlled volumes. They are one of the keys to modern efficient and clean engines. If a fuel injector is dirty or failing, it can present symptoms such as rough idle, engine surges, rich or lean conditions, and check engine lights. Replacing a problematic fuel injector with an engineered to fit TRQ replacement part right away is essential to the health of your vehicle’s engine.
