Some further results ...
I repaired and reconnected the O2 sensor connector in the bay and retested the FV voltage and it was still pegged at around 12v. Perhaps with a running car and an active 02 signal, this voltage would drop to a more appropriate duty cycle (if I understand things correctly ....) ?
I then started the car with a buzzing FV (do not believe this was the case previously, when the folks who installed and "dialed in" this newly built motor 2,500 miles ago). I should mention that - upon other things - the installer had a non-functioning MAP hose connected to the WUR as well as the likely non-functioning FV and "dialed in" the mixture accordingly .... I now believe I am dealing with a different animal.
Once the car was warm ( I had to increase the idle a quarter turn to keep it idling during warm up), my control pressure was at 3 bar (I know, low) and my 02 sensor output voltage - yes, I remember Sals sage advice - stayed at around .1 volt at idle and rose to a steady .4 volt when I gunned it.
I am wondering what my next steps are ..... continue testing the ECU side of things or focus on the WUR pressure issue.
Thanks to all, I could not be more appreciative of everyones input .
