Why does air come out my throttle body after it dies?

I have a 1998 Chevrolet Camaro (base) v6 3.8L.
After I turn on my car and it reaches to the appropriate temp, it idles roughly and starts to shake and loses rpm and eventually dies, if hold on the gas it kills faster. I try to turn it back on but it only cranks, as if it wasn't getting any gas(Iv'e put a new Gas Pump & Filter) And after it dies, air comes out from the throttle body, then it makes a strange pop and stops.
BTW I scanned it with a code reader and these are the code I got:
P0102 Mass Air Flow Sensor Circuit Low Input
P0108 Manifold Absolute Pressure Sensor Circuit High Input
P0171 System Too Lean (Bank 1)
P0172 System Too Lean (Bank 2)
P0300 Random/Multiple Cylinder Misfire
HELP!!
