Question about 2000 Pontiac Grand Prix
/Agree with Dubeone more than likely it is the idler pulleys or the tensioner, but also could be the supercharger pulley. these should not have any play in them. Depending on mileage and how the supercharger was maintained, it may need rebuilding. the impeller shaft bearings may be worn out causing it not to run true during RPM increases or decreases. Hopes this helps ~ Zach

These cars have a lot of problems with all the idler pulleys and the tensioner. You will most likely have to replace them.You may also want to check the harmonic balancer and make sure it is running true.Spin the supercharger by hand with the belt off,it should spin freely with no end play in the shaft to speak of.I hope this helps...Dan
