Throttle Body Cleaning

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.
  1. Check for damage to the air cleaner. If the air cleaner is damaged, replace it (see AIR CLEANER ELEMENT INSPECTION/REPLACEMENT  ).
  2. Remove the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION  ).
  3. Clean off the carbon from the throttle valve and inside the throttle body with a paper towel or a clean shop towel soaked in throttle plate and induction cleaner.
    NOTE:
    • Remove the throttle body to clean it.
    • Be careful not to pinch your fingers.
    • To avoid removing the molybdenum coating, do not clean the bearing area of the throttle shaft.
    • Do not spray carburetor cleaner directly on the throttle body.
    • Use Acura throttle plate and induction cleaner.
