  • Install a new air filter that meets OEM specifications.
  • Reassemble the air filter housing cover and secure it properly.
3. Clean Throttle Body
  • Remove the intake duct connected to the throttle body, using appropriate tools.
  • Spray throttle body cleaner onto a clean cloth and wipe the internal surfaces of the throttle body.
  • Ensure the throttle plate opens and closes freely.
  • Reattach the intake duct securely.
4. Check and Replace Spark Plugs
  • Remove ignition coil connectors and unscrew the coils using a socket set.
  • Take out old spark plugs using a spark plug socket.
