How does Jetta clean the economizer door and injector?

The throttle can be cleaned by itself, but the nozzle cannot be cleaned without tools. Remove the hose at the throttle door with a screwdriver and vice, open the throttle or key, step the NO accelerator pedal to the bottom, then spray the cotton cloth with cleaning aid and wipe it gently. Don't wash it too clean every time, or the idle speed will be high.
