Anti-AFTERBURN Valve
- Disconnect anti-afterburn valve-to-air cleaner hose at anti-afterburn valve (if equipped). Start engine and run at idle. Place finger over hose (intake port). Engine speed should not change. Increase engine speed and quickly release accelerator.
- Suction should be felt at air intake port. If no suction is present or suction lasts for more than 3 seconds, replace anti-afterburn valve.
