Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface.
Disconnect the battery before working on electrical components.

2. Replace Air Filter

Locate the air filter housing.
Unscrew the clamps or clips securing the housing.
Remove the old air filter and insert a new one.
Reassemble the air filter housing and secure it properly.

3. Clean Mass Airflow Sensor

Locate the MAF sensor, usually found in the air intake duct.
Disconnect the electrical connector and remove the sensor.
Use MAF sensor cleaner to spray the sensor elements carefully.
Allow it to dry completely before reinstalling.

4. Inspect and Clean Fuel Injectors

Use a fuel injector cleaning kit or take the vehicle to a professional service if necessary.
If cleaning at home, disconnect the fuel rail and injectors.
Follow the kit instructions to clean injectors thoroughly.
Reassemble all components ensuring there are no leaks.

5. Check Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate to the manufacturer's recommended PSI if needed.
Inspect tires for uneven wear and replace if necessary.
