Question about 1999 Pontiac Grand Prix
Yes valves on my 1999 grand prix supercharger in knocking i want to know whats wrong do i need a motor or supercharger
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.
