  • connects the accelerator cable and, if equipped, the speed control actuator cable to the throttle lever.
  • is not adjustable.
  • cannot be cleaned.

The fuel injector:

  • is electrically operated by the powertrain control module (PCM).
  • has an internal solenoid that opens a needle valve to inject fuel into the lower intake manifold.
