Cleaning and Inspection

- Clean the IAC valve O-ring sealing surface, pintle valve seat and air passage.
- Use carburetor cleaner and a parts cleaning brush to remove carbon deposits. Do not use a cleaner that contains methyl ethyl ketone. This is an extremely strong solvent and not necessary for this type of deposit.
- Shiny spots on the pintle are normal and do not indicate misalignment or a bent pintle shaft.




- If the air passage has heavy deposits, remove the throttle body for complete cleaning.

- Inspect the IAC valve O-ring for cuts, cracks, or distortion. Replace the O-ring if damaged.
