91 Ls4

Thanks, actually no its seems to just hesitate for a spit second and thats it.

Hay guys new user, I have a 1991 Lexus Ls400 i get a vibration from 40-60mph once every so often. It lasts maybe a second or two feels as if my phone/pager vibrates on your belt! The car has been balanced road tested and everything. Maybe someone has had this problem and can help me out.....?
