I have a Grand Marquis Mercury, and my car won't go over 50 miles per hour, like it just won't get no gas or air to the engine or something I don't know. But my question is would that be the Massive Air Flow Sensor that's causing my car not to get the speed it needs?

Lack of acceleration, chugging, hesitating, bogging, misfiring etc. Could be caused by one of the following below:

Start here-inspect and test all the item below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.
