Easy thing to try is different fuel vendor.

Have had this happen to me and switching fuel cleared up my rough idle.

Welcome!

Is your engine shaking only at idle? How does it operate when driving? How many KM has the car been driven? Is the transmission automatic or manual?

So the shaking was happening with the old engine AND it is also happening with the new engine?
Same situation to old engine and new engine. I have change all engine mounts but the result is same. My car's catalytic converter is cancelled. Can be the catalytic converter to cause of this problem?
