My 93 sc has constant, nasty vibration that can be felt even in neutral when rpm's are raised. I'm running the car easy untill I can find a good used blower as my cone bearing is banging like 2 rabbits on crack. The mounts are new, the balancer is new, clutch has never givin problems, u joints are tight. So I'm wondering.. could the fact the bearings are shot on the blower be causing an air mixture proble that is causing the roughness/vibration. I'm at my whit's end on this one and would appreciate any suggestions. Thanks all
