So last night i bought a 98 gtp ive been looking for about 3 weeks and the one i found has high miles 150k+

well theres a slight chatter from the supercharger i can feel it in the nose peice.

now my ? is this what is the most likely cause of the this and how should i go about diagnosing and repair

Im new to the gtp world but not cars so i can do the work myself..

Thanks for any input of help
