Mass Air Flow vibrration Noise

I need help I hear a LOUD vibrating noise kind of like a hum noise when i start the car up and then goes away when its warmed up i checked the air flow and it actually blows out more less sucking in what is wrong please help...

I had humming coming out of the airbox once. The idle air control valve was bad. Give that a try.

Would that cause your car to idle at 2000 rpms in Park?

IAC valve controls the idle through various sensors. A sensor or bad EGR valve will cause idle problems. Try pulling the codes out of the computer. Failing that look for vacuum leaks and spray air intake cleaner around the intake gaskets,vacuum sources, etc. If idle changes look at that part.
