1. Clean off any deposits from the inside of the throttle body assembly.
   1. Push open the throttle valve and wipe off any carbon from the valve and bore using a cloth soaked in non-residue solvent.
   WARNING:

   Make sure that the cloth or your fingers do not get caught in the valve.

   NOTE:

   • Make sure that foreign matter does not enter the throttle body assembly.
   • Do not directly apply non-residue solvent to the throttle body assembly or wash the throttle body assembly. Cleaning solvent may leak into the motor from the shaft and cause problems such as rust or valve movement problems.
   • If there is coating material on the edge of the valve, be careful not to remove it.
   • Push the throttle valve open gently with your finger and check that the throttle valve moves smoothly.

   HINT: 

   If the throttle valve does not open smoothly, replace the throttle body assembly.
