Fuel Injection Service
The fuel injection system's basic parts are the Fuel Injectors, Fuel Pump, Fuel Filter/Lines, Fuel Pressure Regulator and a control module (Computer).
There are additional components like temperature sensors, throttle position sensors, pressure sensors or flow meters involved to adjust the flow of fuel to the engine.
Any one component being out of specification can cause drivability issues or the check engine light to come on.
Fuel injector cleaning can help clean the injectors to maintain the proper amout of fuel going to the cylinders and also clean deposits from the valves and combustion chambers.
