Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the battery to prevent electrical shorts during work.
Allow the engine to cool completely before beginning work.

2. Clean or Replace Air Filter

Remove the air filter cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
Clean the air filter with compressed air or replace it with a new one if necessary.
Reinstall the air filter and air filter cover, ensuring it is secured properly.

3. Inspect and Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Ensure the throttle plate moves freely; check for any sticky areas.
Reattach the intake duct securely.

4. Test Mass Airflow Sensor

Disconnect the electrical connector from the MAF sensor.
Remove the MAF sensor from its housing.
Inspect the sensor for dirt; clean it with MAF cleaner if necessary.
Reinstall the MAF sensor and reconnect the electrical connector.

5. Fuel Injector Cleaning

If fuel injectors are suspected to be clogged, use a fuel injector cleaner kit.
Follow the instructions provided with the kit to clean the injectors.
Reinstall any components removed to access the fuel injectors.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and let it idle to check if the stalling issue persists.
