Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Clean the 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 thoroughly.
Reinstall the air intake duct and reconnect any hoses.

3. Replace Fuel Filter (if applicable)

Locate the fuel filter (refer to the owner's manual for the exact location).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using the appropriate tool.
Install the new fuel filter, ensuring the correct flow direction.
Reconnect the fuel pump fuse and prime the fuel system.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket wrench.
Extract the spark plugs with a spark plug socket.
Inspect the spark plugs for wear and replace if necessary (use manufacturer-recommended spark plugs).
Reinstall the spark plugs and ignition coils, tightening to the specified torque.

5. Test the MAF Sensor

Disconnect the MAF sensor connector.
Clean the MAF sensor with MAF cleaner.
Reconnect the sensor and check for proper function using a multimeter if applicable.
