Yep, both our cars, simultaneously, by same method and personnel, yet mine retains this vibration that I want to eliminate.

It is in the head and cams somewhere, I will find it when it gets a little warmer and I can start swapping out parts. I think first I will put the original cam wheels back on, then if that doesn't show a change, the original factory cams go back in, and if that doesn't show a change, I have a known good std valve 2L head I can swap on and see what that does (it would show that the valves are somehow involved). If none of that works, I could circle back to the fuel injection system, but I really doubt that is the problem. However, I will noid light each injector before I start any of this. The cause will eventually emerge, no doubt!

Is it a vibration or a mechanical noise? I cannot think of anything in the head causing a vibration. Mechanical noises, yes.

Vibration. Not a mechanical noise.
