Fuel injector service is a set of procedures aimed at correcting or maintaining the components that control the fuel that enters your engine. Fuel reaches the engine from the tank by way of pressure from the fuel pump. The fuel injectors respond to electrical impulses from the ECU (Engine Control Unit) to open and close, spraying fuel into each of the cylinders in just the right amount and at just the right time.
There is typically one fuel injector for each cylinder, mounted just inside the top of the combustion chamber. Over time, those fuel injectors can become clogged with carbon from the combustion process and debris from dirty fuel. During a fuel injector service, not only are the injectors cleaned, but other related concerns and components are addressed at the same time in order to restore proper fuel system function and improve engine power and efficiency.
