Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect for dirt and blockages.
Install the new air filter, ensuring it fits snugly.
Reattach the air filter cover and tighten screws/bolts.

3. Inspect and Clean Fuel Injectors

Remove the fuel rail according to manufacturer specifications.
Clean the fuel injectors using a fuel injector cleaning kit.
Reinstall the injectors into the fuel rail and reconnect.

4. Check and Replace Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate tires to the recommended PSI listed on the driver's side door jamb.
Inspect tires for uneven wear and replace if necessary.

5. Verify Mass Airflow Sensor (MAF) Functionality

Disconnect the MAF sensor connector.
Clean the MAF sensor with MAF cleaner spray.
Reconnect the sensor and clear any diagnostic codes if present.
