NOTICE
• Be sure to use the recommended cleaning
agent.
• Do not spray the cleaning agent directly
onto the ISC valve or throttle bodies and do
not immerse them in the cleaning agent.
• To prevent scratching the components, do
not use a brush, metal file, or other abra-
sive tool.
• Do not clean with compressed air.
• Do not allow the removed deposits or for-
eign materials to adhere to the sealing sur-
faces of the O-ring.
• Do not scratch or deform the ISC valve or
air passage; otherwise, poor starting per-

or uncontrollable engine speed could re-
sult.

dicated in the illustrations. If the cleaning
agent attaches to the ISC valve or enters
the throttle bodies, thoroughly wipe it off.
