high fuel consumption / cold start / rough idle

[scirocco at vintagewatercooleds.com (Eric S)]

Fuel pressure tests would be ideal...especially control pressure going
from the warm up reg to the fuel dist...as for how hard that is...I dunno
where to get the tools to do it.

Difference on the O2 sensors is just one has the connector, one doesn't
(you have to splice).
