01 ws6, m6 when accelerating.... i can only accelerate very slowly... if i accelerate too fast the car stalls, no matter what gear it's in. I can hear a pretty loud buzz towards the rear of the car, it is like when you turn the key on and the gas pump buzzes except it does not stop buzzing. When getting off the expressway, car turned off, would not turn on, pumped gas and then car turned on again, but was still stalling. Tank was not empty because it only took $20 to fill up. Appreciate the help thanks

 

it might sound like your fuel pump. when the car starts and you hear the buzzing, thats the fuel pump. if you hear that at WOT, it might be going out, feeding less fuel, which would explain the stalling at WOT. just a thought.
