The air fuel ratio has more air than it should and not enough fuel. It could be the result of an O2 sensor, a vacuum leak.

Lean fuel condition could be caused by one of the following below:
1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor
