1976 Ford Courier Automatic TransFACTORY OEM SERVICE PROCEDURE

Anti-AFTERBURN Valve

  1. Disconnect anti-afterburn valve inlet hose and run engine at idle speed. Press a finger tightly over inlet hose opening. This should not cause engine speed to vary.
  2. Hold a finger lightly over inlet hose opening. Increase engine speed and quickly release accelerator. Air should flow inward for a few seconds. If the valve passes air inward for longer than 3 seconds, or does not pass air at all, replace the anti-afterburn valve.
