Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool down before starting work.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Carefully pull out the spark plugs using a spark plug socket.
Inspect the spark plugs for wear or fouling.
If necessary, replace with new spark plugs (ensure correct gap and type).
Reinstall ignition coils and connect wiring harness.

3. Clean or Replace the Throttle Body

Remove the air intake duct connected to the throttle body using a screwdriver.
Clean the throttle body using throttle body cleaner and a soft cloth, ensuring no debris enters the intake manifold.
If the throttle body is excessively damaged, replace it with a new one.
Reconnect the air intake duct securely.

4. Check and Replace Fuel Filter

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter using a line wrench.
Replace the old filter with a new one, ensuring proper orientation.
Reconnect fuel lines and reinstall the fuel pump fuse.

5. Inspect and Test the MAF Sensor

Disconnect the MAF sensor connector.
Use a multimeter to check the voltage output while the engine is running (consult service manual for specifications).
If the MAF sensor is faulty, replace it with a new one, and reconnect wiring.
