Why does my buick "shutter" while driving ? on 1997 Buick LeSabre

Car shutters while driving esp. when i try 2 go faster & apply pressure on gas pedal I almost immediately "feel the steering column - shake/shutter along with the front end feeling as its shaking/shuttering also. We replaced the inner tie-rod (others are fine im told) tires are practically brand new. HELP !!!

It could be several thins. Worn motor mounts, bad steering or suspension component, a bad axle shaft, bad wheel bearing. I recommend you take it to a repair facility and have it properly inspected.
