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.
