RE: 1999 A4 1.8t weird intake sound above 3k - stalls - sucking air sound
You have a massive boost or vac leak. Thats why the car is stalling. You probably have it to where you can make some boost, but when you change gears, its stalls. Its basically like a bov that is open at idle, you leak a massive amount of metered air.
