I just got a 1983 Alpha Romeo GTV6 and the person that sold it to me stated that it requires a new clutch.When I drive it has power and then when you are driving it feels like you are going into neutral with car going no where and car is reving. Then it picks up again with power and moves with power in gear.Then again when you are in first gear, 2nd or third, it feels at times power , then looks like in neutral with engine running, then kicks back into gear when gear shift is in either 1st, 2nd or third gear. Anyone knows what this could be?
