Thanks for the continuing thoughts and responses.
My next session with the car, which will probably be tomorrow night, I will take off all three belts, crank it and rev it up once to see if the vibration goes away.
If it were the flex plate, it would seem that it would happen when you rev it up, wheter or not the vehicle is under way.
Thanks everyone, I haven't set it afire yet,
PS When I think further about this. The vibration is so bad, I believe I would see a heavily pulsating belt if the problem were an accessory. I will try it anyway. LB
