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.
