Sensor Plate Clearance Adjustment

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1987 Volkswagen Scirocco, 1987 Volkswagen Quantum, 1987 Volkswagen Jetta, 1987 Volkswagen Golf, and 1987 Volkswagen GTI. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove fuel distributor from airflow sensor housing. Turn distributor upside-down to access stop screw for control piston. This will adjust free play travel range of sensor plate lever.
  2. Turning screw clockwise will increase clearance by keeping control piston higher in fuel distributor during operation. Turning screw counterclockwise will decrease clearance by allowing control piston to extend further out of fuel distributor during operation.
  3. Adjusting stop screw 1/4 turn (90 degrees) will make .05" (1.3 mm) difference at sensor plate. Idle speed and CO (current reading) must be checked.
