With the engine running or cranking, listen to the sound from each injector with an automotive stethoscope and verify the injectors are all clicking the same. If you don't have a stethoscope, place the tip of a crew driver against the injectors and press your ear against the handle of the screwdriver. Feel the operation of each injector. Prior to installation, lubricate the O-rings with a light film of clean engine oil. Push the top of the injector straight into the fuel rail receiver cup, taking care not to damage the O-ring. Slide the open end of the injector clip into the top slot of the injector, onto the receiver cup ridge, and into the side slots of the clip. Install the fuel rail.

First remove the air cleaner assembly and relieve the fuel system pressure. Disconnect the negative battery cable and remove the fuel pressure regulator if necessary. Remove the Torx screw and carefully pry off the injector cap. Use a small screwdriver to gently pry the injector from the throttle body. Peel off the upper and lower O-rings from the injector, making sure to retrieve the lower O-ring if it is not on the injector.
