Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal for safety.
• Allow the engine to cool before beginning work.

2. Clean Throttle Body

• Remove the intake duct to access the throttle body.
• Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
• Reassemble the intake duct securely.

3. Replace Fuel Filter

• Locate the fuel filter; it may be mounted on the chassis or in the engine bay.
• Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.
• Disconnect the fuel lines (using appropriate safety measures) and remove the old fuel filter.
• Install the new fuel filter, ensuring the flow direction is correct.

4. Replace Spark Plugs

• Remove the ignition coils or spark plug wires (mark their positions if necessary).
• Use a spark plug socket to remove the old spark plugs.
• Inspect the old plugs for wear; replace with new plugs according to manufacturer specifications (check gap).
• Reinstall ignition coils or spark plug wires securely.

5. Inspect and Clean MAF Sensor

• Disconnect the MAF sensor connector.
• Remove the sensor from the air intake duct.
• Use MAF cleaner to gently clean the sensor element without touching it.
