Locate the fuel filter; consult the service manual if necessary.
Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate line removal tools.
Replace the old fuel filter with a new one and reconnect the fuel lines.
Reinstall the fuel pump fuse and prime the fuel system.

4. Clean or Replace Throttle Body

Remove the intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
If the throttle body is damaged or excessively dirty, replace it with a new unit.
Reconnect the intake duct securely.

5. Inspect Ignition System
