Mike;

If the vibration stops when the clutch pedal is depressed and the clutch is dis-engaged from the pressure plate, I would have to think it is the clutch itself, or the pressure plate........outside chance it could be a problem with the flywheel.....

I would pull the trans and check this out before running the car much more.vibrations don't usually go away on their own and can and do lead to other problems down the line....if the vibration is severe enough, it will eventually cause other things to work their way lose and cause more problems...

also, check out the pilot bearing in the end of the crank while you have things apart.....

My guess, is the clutch disc itself may have lost some of it's material and throwing things out of balance, just my hunch.....
