I just tried this and its still bouncing all over the place.  the only
difference with the vacuum disconnected is that the range is now higher
(its bouncing from 35-45 instead of 28-40).

Also, I took out all my injectors while the fuel gauge read about 30psi
and watched.  All the injectors stayed dry, no dripping.  So, I am now
doubtful if there is one that is leaking (although I'm not 100 sure yet).

Its still running rich and still sounds horrible.

Thanks,
