I have a 3.8 v6 89 cougar that has a sound of almost like marbles rolling in the supercharger area coming out of it, although i am not sure if it is the supercharger. we have had issues with the Crank shaft sensor for firing in the past, and its been a big issue. the car is also running very rough. Any thoughts on what it may be? it doesnt sound like an engine knock but it is this horrible noise that definately means something is wrong. thanks for the help
