  • Remove the air filter housing cover by loosening the screws or clips.
  • Take out the old air filter and clean the housing if necessary.
  • Install the new air filter, ensuring it fits securely.
  • Reattach the housing cover and tighten screws or clips.
3. Clean Fuel Injectors
  • Tools Required: Fuel injector cleaning kit, safety goggles, gloves.
  • Disconnect the fuel line from the fuel rail using the appropriate tool.
  • Attach the cleaning kit to the fuel rail and follow the manufacturer's instructions for cleaning.
  • Reconnect the fuel line and ensure there are no leaks.
4. Replace Spark Plugs
  • Tools Required: Socket set, torque wrench, replacement spark plugs.
  • Remove the ignition coil or cover to access the spark plugs.
  • Unscrew and remove each spark plug using a socket wrench.
