like I asked back in post 18.
does the FV vibrate with the key on?
if the FV does not work it will make it go lean, thus the need to go rich at idle to make it run.

the FV is pulsed on and off so I don't know if you will see 12v or not.
easiest check is does it vibrate.
there is a way to look at the duty cycle on the 911 but I have never done it on the 930 so not sure where you would connect to. you have to use a dwell meter to look at the signal.

I have had the same issue but I have the euro CIS. I had to run very rich at idle, then I am at 15.2 at cruise and also had it go lean when I would lightly accelerate. air leaks for me
