Make sure you have vacuum going into the cab from the intake manifold. (If you do and still no air, the problem is in the controler.
I'm not a mechanic / technician but I was looking at a picture on fordparts.com and it shows the mass airflow sensor located around the engine air filter assembly on the drivers side for a 2006 Ford Expedition

Check for a broken vacuum line by the battery. These lines get brittle and break with age.
I had the same problem on my Expedition. The heater core needed to be replaced. Cost around 700.00.
I had the same problem with a 1999 Expedition and it was a bad plug. Ford had a problem also with the plugs blowing out. It cost me about 1200.00
What causes the generator to burn out after replacing the alternator
will the transmission causes my 1999 ford expedition to bog down & sputter when accelerating the 4.6liter engine.
On a 1998 Ford Expedition : The Mass Air Flow sensor is located between the engine air filter and the big rubber engine air intake tube ( it is INSIDE the circular shaped plastic housing , you will see where the wires go inside )
starter motor need overhaul
