Sounds like you have an intermittent problem and you checked the voltage while the problem wasn't occurring. Also, Ford likes to be different than everyone else. You can't read the voltage on the mass air flow sensor. You have to read the frequency.
The logical suspect is the sensor, but if you want to check it first, you'd need to drive the vehicle with a scanner to view live sensor data. Thank goodness for fault codes with intermittent problems so you know where to look. Be sure to check the wiring to the sensor too, particularly the terminals in the connector.
