1997 Ford Windstar Question: Makes a vibrating sound
So hard to guess at a sound with out being able to drive the vehicle first hand and experience the problem. A vibration like you describe is likely to be the exhaust rubbing due to a filed exhaust rubber hanger or engine mount that is allowing the engine to flex "too much". Vibrations on acceleration are often caused by damaged or cracked exhaust heat shields. - patrick mannion
The vibrating is heavy and comes randomly while I'm driving any suggestions on what could be causing my problem?
A knocking noise from the upper engine area may indicate a loose intake runner. Our technicians tell us if this is the case, replacement of the upper intake clamshell will be necessary.
