Research the specific error codes to understand the potential issues.

3. Inspect and Replace Faulty Components

Spark Plugs and Ignition Coils:
- Remove the engine cover if necessary.
- Disconnect the ignition coil connectors.
- Unscrew and remove the ignition coils using a socket set.
- Inspect spark plugs for wear; replace if necessary.
- Install new ignition coils and reconnect connectors.
Mass Airflow Sensor:
- Locate the MAF sensor in the intake duct.
- Disconnect the electrical connector and unscrew the sensor.
- Inspect for dirt or damage; clean with MAF cleaner or replace.
Oxygen Sensors:
- Identify the sensors in the exhaust system.
- Use an O2 sensor socket to remove and replace any faulty sensors.

4. Check and Replace Gas Cap

Confirm that the gas cap is tight and in good condition.
If damaged, replace with a new OEM gas cap to ensure proper sealing.
