Question on a procharger p-1sc-1

I just bought a '02 ws6 with a procharger on it. I noticed that the Proflow anti-surge valve was seized in the closed postition. Could this be causing the car too run very rich on both banks?

No, but it can cause serious damage to your head unit when you let off the throttle. With no evacuation for the air pressure it can only go back into the had unit putting a lot of stress on the bearings.

Get that fixed before you take the car into positive pressure.

How rich is it running?

Not sure yet, I just ordered an Aktron code reader to see if I can find something. SES light came on and the local auto parts place scanned it and it only read running rich on both banks. I just purchased the car and while I was looking underneath I noticed the valve had a little rust on it. When i took it apart I noticed it was basicly stuck in closed position.
