The vibration can be felt at cold start / idle when the engine need to run around 1250 rpm or at cruising under a small load and around 1250rpm at any transmission speed. Vibration is gone over 1400 rpm and under 1100. The vibration is felt in the driver seat, center console and resonating in the roof. Gasket were changed before and after catalyst which solved only partially the vibration... it doesn't vibrate anymore in the roof.
