soo im starting to really worry about my 99 Pontiac
Grand am and my car vibrates rougher than normal
when put in gear (Drive) with my foot on the brake
and it only does in the (D) gear and when parked
on a hill running when it rolls back slightly why is
vibrating soo violently? "engine runs fine"
Could be a failing engine mount as you seem to feel it more when there is a load against it.
