Sell the car! It's gone bad, and it's probably too late to do anything. Nevermind... you said you didn't want to hear that. Okay... first thing to check is that the turbo bypass valve is in good shape. You can't miss it - it's the small black plastic cylinder sticking out from the long pipe that runs between the throttlebody and the intercooler. It'll have two large hoses going into it (one from the aforementioned pipe) and a small vacuum line. Get a length of vacuum hose, pull the vacuum hose off the bypass valve, and connect your hose to the valve. Suck and blow on the hose. If you can do both or either, you need a new bypass valve, and this will cause your stalling. -Justin
