OK, so I'm driving to work ('00 B5 ATW) and a go to pass a truck, as I put my foot on the accelerator the engine loses power(lags) for just a split second and then takes off again like normal. I continue to drive to work. When I go to leave work, I
start the car up and the CEL light comes on and I'm thinking "Great now what?". So I get home and check the codes out, they are: 17521 - O2 ...
