Order of inspection
P2279 Intake Air System Leak Medium
The P2279 code means the computer sees more air going into the engine than the airflow sensor is measuring, so there is a leak in the intake after the sensor. It often comes with lean codes and a rough or high idle. You can drive with caution, but a lean mixture left alone can damage the engine and the catalytic converter.
