Im going on one 2-3 years with this issue. Not a big deal.

My car has the same issue. My guess (i don't think 300 dollars is worth it for the 1 second inconvenience, so i have not replaced it yet) is the check valve is the fuel pump. If it is, then before you start your car, turn the key all the way, but stop at the run position (the last spot before you crank it) this will cycle the fuel pump. Give it 5 seconds to pressurize, and then start it. When you shut your car off, the fuel in the line starts to seep back into the pump/tank. the check valve is supposed to keep some pressure in there, so if that valve is bad, then when you start your car will burn whatever fuel is in the line and then die. So when you Rev the engine, your cranking up the fuel pump.

Sounds like the mass airflow sensor...... check to see if it has bugs or some kind of foreign object blocking the opening

While the engine is cold, try starting it and giving a little gas while you start it. If it starts, release your foot and see if it keeps running. If it stalls out, start it again (by giving a little gas again) and then keep your foot on the gas slightly to keep it from going to it's normal idle. Once the engine is warmed up, let off the gas and see if it stays running again. If it does then you need to clean/reaplace the IAC valve that is on the throttle body.

If you can, remove it and clean it out with carb cleaner (like B-12) and an old toothbrush. It could save you some money from having to replace it.
