Is these two above normal in your opinion? Car does not throw CEL and drives otherwise real well.

Then - another noice the patient shows, is a 'chirp' as I press the gas a bit from the idle. This chirp does not show except when I take off from standstill.

All above can be seen/heard on the video at this link:

The chirp is a classic loose spark plug issue.

Thank you tommy, the chirp is gone
One plug was very slightly 'not tight enough' and after going thru all plugs, car sounds as it should and runs again a tad better:dance:

What’s the word I’m thinking if? It’s validation, oh yeah.
