I have a code po171b(system too lean), stalls when coming off of the throttle and sometimes when you are sitting idling. I got about 120 kms to a third of a tank. What could be the problem.

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.
