  • Reattach the air filter housing cover.
3. Check and Clean Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle body, removing carbon deposits.
  • Reinstall the intake duct securely.
4. Replace Spark Plugs
