Bob, just to poke fun at you, I like your first sentence however the verbiage in the second sentence does
not seem to agree with the next paragraph!
While the above ideas all have merit, I tend to think by you saying the vibration is only happening during idle while accelerating/deaccelerating in neutral, my guess is the flywheel has been lightened a tad too much which is showing up from the impulses of each cylinder firing. When you are driving it, items such as transmission cluster, driveshaft, U-joint, wheels, etc. all are mass that adds to the weight of the flywheel which in-turn masks those impulses.
