If you notice your vehicle is spittering and sputtering, it could be that you need a fuel injection flush. A fuel injector is nothing more than spray nozzle. With mechanical injectors, a spring loaded valve allows fuel to sq**rt out of the nozzle when line pressure overcomes spring tension that holds the valve shut. With electronic injectors, a spring-loaded solenoid pulls open a pintle valve or ball type valve when the injector is energized by the computer. This allows the pressurized fuel in the fuel rail to flow through the injector and sq**rt out the nozzle.
