Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean the Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a clean cloth to remove carbon buildup inside the throttle body.
Reattach the intake duct securely.

3. Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils by unscrewing the bolts and pulling them out gently.
Remove the old spark plugs using a spark plug socket; ensure to note their condition.
Install the new spark plugs with the correct torque specification (typically 15-20 Nm).
Reinstall the ignition coils and engine cover.

4. Check and Replace Fuel Filter

Locate the fuel filter and relieve the fuel system pressure (consult service manual for procedure).
Disconnect the fuel lines from the filter using appropriate wrenches.
Replace the old fuel filter with a new one, ensuring the correct orientation.
Reconnect the fuel lines and check for leaks.

5. Test Fuel Pump Operation

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check initial fuel pressure.
If the pressure is below specifications, replace the fuel pump as outlined in the service manual.
