Socket set
Torque wrench
Screwdrivers
Multimeter

2. Inspect and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use the socket set to remove the fuel filter.
Replace with a new fuel filter, ensuring proper orientation.
Reconnect the fuel lines securely and check for leaks.

3. Clean or Replace Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body.
If damaged, replace the throttle body with a new one.
Reassemble the air intake duct securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers to access spark plugs.
Use the socket set to remove old spark plugs.
Check the gap on new spark plugs and install them with the correct torque specification (typically 15-20 Nm).
Reinstall ignition coils securely.
