WARNING: This page is about a different car, the 1983 Volkswagen Vanagon. However, it is still accessible from the selected car via links, so may be relevant.
  1. Run engine until warm. Mount tachometer sensor (US 1324) on valve cover and connect to battery. Attach tachometer to sensor and check idle speed.
  2. If adjustment is needed, loosen lock nut on idle screw. Turn in to increase idle, out to decrease. Apply thread sealer and tighten lock nut.
