Anti-AFTERBURN Valve

  1. Warm up engine and run it at idling speed. Disconnect air hose (air control valve-to-air pump) at air pump. Place a finger over air hose opening and make sure that air is not sucked into air hose at idling speed.
  2. Increase engine speed more than 3000 RPM then decrease engine speed rapidly. Make sure that air is sucked into air hose for a few seconds while decelerating. Replace air control valve, if necessary.
