I did not see any pending codes on Torque.
I will check for misfires, but again, it does not feel like it is misfiring... I just did not get a chance to hook it up today.

I wanted to add more "description" of the vibrations.
So - sometimes it feels like the engine was not balanced. I am not sure if that is the best description, but feels like at certain rpms it would be bouncing. Again, like a wheel that needs to be balanced.

Then, the "metallic" noise, is not per say metallic. I was wrong saying that.
It is much more like driving over the highway rumbling strip. Kind of hard rumble. Of course, not to the same extent in terms of the force, but similar feel. And it is felt both ways - steady speed or coasting. Under WOT not so much, though. And only within certain rpm speeds - mainly 2200-2400.
