Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the engine to cool before beginning any work.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and inside the throttle body.
Reinstall the air intake duct, ensuring all clamps are secure.

3. Replace the Air Filter

Locate the air filter housing and open it, usually secured with clips or screws.
Remove the old air filter and inspect for dirt and damage.
Install a new air filter, ensuring it fits snugly in the housing.
Close the air filter housing securely.

4. Check and Replace Spark Plugs

Remove the ignition coils using a ratchet and socket.
Extract the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace them with new ones if necessary, following the manufacturer's gap specifications.
Reinstall the ignition coils, ensuring they are seated correctly.

5. Test and Replace the Mass Airflow Sensor (if necessary)

Disconnect the MAF sensor connector and remove it from the intake.
Clean the MAF sensor with MAF cleaner; if still malfunctioning, replace it with a new sensor.
Reinstall the sensor and reconnect the connector.
