2003 Oldsmobile Alero Question: why does my car shake when in drive but not in motion? at a stop it will shake-

until i take off. what causes this to happen? -
Answer 1
Have compression checked, and for vacuum leak(s)! Low compression, or misfire, on one or more cylinders can cause this, a vacuum leak also! It is still there when driving down the road, just not as pronounced. -
Answer 2
Also , just a thought......maybe bad engine mount(s)? -
