This vibration only happens occasionally and usually at around fifty km/h and seventy five km/h.When accelerate hard the vibration goes away. Only happen when gently accelerate and when reach speed around fifty to seventy five km/h the vibration comes on.

Letting go the accelerator the vibration goes away.
And yes there is a check engine light ( code p0031 ).
Is it possible that this is related to the code?

And I notice that when accelerating full from a stand still, it seems to hesitate shifting in to the second gear.
I than put it in "N" and back to drive before it shifts up.

Tire problems come to mind for me like the tires are not balanced or one of them has a defect. Can you try to rotate the tires front o back to see if that helps?

The code is an oxygen sensor that has gone out and needs to be replaced. Bank 1 sensor 1

Please let us know what happens.
