Silly question - have you opened the hood and looked around? My guess is that you've popped off an air hose. Most likely a hose on the throttle body, or between the air mass meter and the throttle body. This may sound silly, but when the same thing happened to me, the big fat hose leading to the throttle body had popped off from the high boost (something you'll get when accelerating hard in third). Now tons of unmetered air can come into the engine. With the throttle closed, the car idles OK. But when you step on the throttle, the throttle plate opens up and air comes into the engine. But the Air Mass Meter doesn't see that air, so the engine control doesn't give any more gas. The mixture goes lean (lots of air, no gas), and the engine runs like crap.
Since you say the gauge goes into the yellow then nothing happens, I'll further my guess by saying a hose is just barely in place, or maybe has split. Things are OK untill you get boost, the the pressure pushes the hose off, and its all air/no gas time. First, with the engine off, grab every air hose and make sure it's on tight, and that all the hoses look OK. Make sure there aren't any hoses hanging free. If you don't find anything, start the car, and with it idling, start moving hoses, pushing on them, tugging them. See if the idle changes all of a sudden - if it does inspect that hose, both ends AND the lenght. I had a Fiat that wouldn't run right (yeah, I know, it's normal...). When I pressed down on the main air hose to the throttle body, the car stalled. Turned out there was a split in the hose underneath. Under load the split opened up and let in extra air. When I pressed on the hose while the car was idling, it let in extra air, and the car stalled.
Good luck!
