could this be a bad engine mount or transmission problem?
Car shaking when going uphill? on 2000 Acura TL
A diagnostic check is needed....try my shop...call 973-483-4489
Could be an EGR problem causing a lean condition/ all the EGR gasses being allocated to only a few cylinders (common Acura problem) or a failed ignition coil but needs to be properly checked out.
