You can remove the belt from the super charger and see if knocking persists. Car will run w/o super charger. Plan to spend about $300 for a remanufactured super charger.

Lean fuel code error on a 1999 Pontiac Grand Prix GTP,3.8L motor

It is the boost bypass valve. The plunger will move with only enough throttle as it is connected to the throttle body.
The bypass solenoid you need is for the Eaton M90, the supercharger on your car. You can very likely get this part from zzperformance.
