was low grade rumble

["Jeff Goldberg" <jeffgold@erols.com>]

Since I did not get any replies explaining the phenomenon, can 4KQ owners at
least let me know if my car is unique or if this rumble is normal in this
car?

TIA,

Can someone explain to me where this rumble sound / vibration is coming
from? What effect should a locked differential have on an idling engine in
neutral? There is certainly something I am not understanding here. Can
anyone help? - 86 4KCSQ
