Hey guys, I brought a 2002 A6 2.7t quattro with 90000miles on it about 6 months ago. Everythings been running smooth until recently, at first i had trouble with accelerating around 60+ there would be little or no response when the pedal is down half way. Now the car would come to a complete stop when I am not on the gas, it feels almost like driving with the brakes on. If I accelerate to about 60 and just it ride the car would come to a stop in about 3-4 secs. Also there seems to be a loud vaccum like noise when Im on the gas. This is my first car so i have little or no experiences, any comments or advice would be appraciate thanks!

 

Do a forum search on vacuum and hoses. It sounds like a hose, or TBB or diverter valve, etc.
