So my 1999 9-3 has a brand new glitch........... When I put my foot hard to the pedal the engine cuts out momentarily. I get multiple cut outs if I leave my foot down on the pedal, just one if I back off the gas. The car runs perfectly if I am not agressive. The boost gauge moves to the third bar at about the time the engine cuts. I don't yet understand the technology but I think it has something to do with to much boost. Any ideas as to what is causing this?
