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.

I have found on those Fords that it's very common for the rubber hoses or connectors to suck a hole right through them. Listen for a hissing noise and follow it to it's source.
