Locate the fuel filter (usually along the fuel line).
Use a socket set to remove the filter.
Install a new fuel filter, ensuring the flow direction matches the original.
Reconnect any hoses and secure all clamps.

3. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Using a spark plug socket, remove the old spark plugs.
Check for wear and carbon buildup on the plugs.
Install new spark plugs, tightening them to the manufacturer’s specified torque (typically 13-20 lb-ft).

4. Test and Replace Ignition Coils (if necessary)

Disconnect the ignition coil connectors.
Remove the coils using a socket set.
Test the coils with a multimeter to ensure they are within specifications.
Replace any faulty coils with new ones, securing them and reconnecting the electrical connectors.

5. Clean Throttle Body

Disconnect the throttle body from the intake manifold.
Use a throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body, ensuring all gaskets are intact and securing it with the appropriate torque.
