I've been down this road listened to people tell me it was the engine it was a bad pressure plate...all I'm saying is check the external easy stuff first don't tell the guy that he needs the rotating assembly machine shop balanced as the first move...for years Ive seen it on here its always the most invasive expensive thing given as advice. I'm glad I know what I'm doing and can keep a car running... feel bad for those that ask here. OP do me a favor PLEASE come back here and tell us what it is/was... :lol:
