Not sure about that, My 4.7 is super smooth at idle.Is it not normal to vibrate a little at idle?
My 4.7 GTS doesn't shudder or run rough but there is a clear vibration in the interior at idle. The RPM moves ever so slightly up and down but it was never the smoothest or most refined engine in the world.
