Use a wrench to disconnect the fuel lines from the filter, being cautious of fuel spillage.
Remove the old fuel filter and install the new one, ensuring the direction of flow is correct.
Reconnect the fuel lines securely.

3. Clean or Replace Air Filter

Locate the air filter housing, usually situated near the engine.
Open the housing and remove the air filter.
Inspect the filter; if dirty, replace it with a new one. If it's reusable, clean it according to the manufacturer's instructions.
Reassemble the air filter housing.

4. Clean Throttle Body

Disconnect the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to clean the interior surfaces.
Reattach the throttle body and ensure it is securely fastened.

5. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coils to access the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect for wear and replace with new plugs if necessary, following the manufacturer’s specifications for gap and torque.
Reinstall the ignition coils securely.
