WARNING: This page is about a different car, the 2009 Honda S2000, 2008 Honda S2000, 2007 Honda S2000, and 2006 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not insert your fingers into the installed throttle body when you turn the ignition switch ON (II) or while the ignition switch is ON (II). If you do, you will seriously injure your fingers if the throttle valve is activated.

Check for damage to the air cleaner. If the air cleaner is damaged, replace it (see AIR CLEANER REMOVAL/INSTALLATION ).
Remove the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION ).
Wipe off the carbon from the throttle valve and inside the throttle body with a paper towel soaked in throttle plate and induction cleaner.
NOTE:
- Remove the throttle body to clean it.
- To avoid removing the molybdenum coating, do not clean the bearing area of the throttle shaft (A).
- Do not spray the cleaner directly on the throttle body.
- Use Honda genuine throttle plate and induction cleaner.
