Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Clean or Replace the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft brush. Ensure the throttle plate operates smoothly.
If the throttle body is damaged, replace it with a new one following the manufacturer’s specifications.

3. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable).
Use a socket wrench to remove the ignition coils and spark plugs.
Inspect the spark plugs for wear; replace if needed with OEM parts.
Reinstall the spark plugs and ignition coils, ensuring they are torqued to manufacturer specifications.

4. Check and Replace Fuel Filter

Locate the fuel filter and inspect for clogs.
If the fuel filter is dirty, replace it with a new one according to the service manual.
Reconnect all fuel lines and ensure there are no leaks.

5. Clean or Replace the Mass Airflow Sensor

Disconnect the MAF sensor connector and remove it from the intake.
Clean the sensor with MAF cleaner; if damaged, replace it with an OEM unit.
Reinstall and reconnect the MAF sensor.
