Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs using a spark plug socket.
Inspect spark plugs for wear; replace them if necessary with OEM or equivalent parts.
Reinstall spark plugs and ignition coils, ensuring proper torque specifications (typically 15-20 Nm).

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body, ensuring to remove carbon deposits.
Reattach the air intake duct securely.

4. Check and Replace Fuel Filter

Locate the fuel filter (consult service manual for exact location).
Relieve fuel pressure in the system by removing the fuel pump relay and starting the engine until it stalls.
Disconnect fuel lines from the filter and replace the fuel filter with an OEM part, ensuring correct orientation.
Reconnect the fuel pump relay and check for leaks.

5. Inspect Air Intake System

Check the air filter for clogs and replace if necessary.
Inspect intake hoses for cracks or loose connections; replace if damaged.
