- Install injector sub-wire to throttle body using a NEW "O" ring. Assemble upper and lower bodies with NEW gasket. Install and tighten upper-to-lower body attaching screws to specification. See TORQUE SPECIFICATIONS . Ensure injector sub-wire is routed in throttle body groove and install sub-wire cover. Install fuel injector and TP sensor.
