My 197 was in for a exhaust manifold replacement, but since it got back I have a quite heavy vibration in the throttle pedal from around 3000 to 5000 rpm. Any idea what might cause this?
I've recently mounted an upgraded torque link and the vibration in the throttle became even worse. I've thought I had changed all engine mounts by now, but seems there's also one near the timing belt. Guess what mount caused the vibration...
