Could it be a engine problem?? My W140 used to have vibration when engine is hot. And when you hit the accelerator, it vibrates even more. And I took the car, and find out that couple of the cylinders are not firing. So, they just replace the connector for spark plugs/ignition wires. After, the car runs smoothly.
