Use a socket set to remove the fuel filter.
Install a new fuel filter, ensuring the flow direction is correct.
Reconnect any lines and secure them with appropriate clamps.

3. Clean or Replace Throttle Body

Remove the air intake duct connected to the throttle body using a screwdriver.
Use throttle body cleaner and a soft cloth to clean the throttle body, ensuring no residues are left.
If necessary, replace the throttle body if it shows signs of significant wear or damage.

4. Replace Spark Plugs

Remove the ignition coil covers using a socket wrench.
Disconnect the electrical connectors from the ignition coils.
Remove the spark plugs using a spark plug socket and replace them with new ones, ensuring they are gapped to manufacturer specifications.
Reconnect the ignition coils and cover.

5. Inspect Exhaust System

Visually inspect the exhaust system for cracks, rust, or blockages.
If the catalytic converter is damaged or clogged, replace it following manufacturer specifications and torque values.
