Engine stalls on start up

[MVQ45]

My 2002 Q45 frequently stalls on startup. When it starts up, I get a low idle, then the engine stalls. This is not all of the time, only sometimes.

A friend who had a I35 had a similar problem and he said it had to do with the "flapper value" (no idea what this is) in the fuel control line and the electronic controls. He said that if I didn't get it fixed soon, I risk blowing out the computer chip because the power transitors that control the fuel control blow out and then the computer IC blows out. Has anyone else heard of this problem?
