I'm a diyer, so take this for what's it's worth:

Regarding your first question...the relationship.

The 2 sec. vascillation of voltage on the O2 sensor between .2v and .9v and the 6.6v - 7.2v reading on pin 3(50 per cent duty cycle) to me are somewhat synonymous.

Not sure I understand the tail end of your 2nd question.

The final post in the following thread might be of interest if you're trouble-shooting a mixture control issue.
