Mine used to be a pig when cold - it'd idle fine or run @ 2,000 or over, but not inbetween. Rebuilt adjustable WUR fixed that.

#2 sounds to me like the idle mixture may set be too lean (or the cold control pressure is too high). Does it surge at a constant 2600-2800 RPM with no boost?

You have stock cams? Mine really hates the idle set for 950 with SC cams (but it's fine when either fully cold or fully hot, just not between 80-160 degrees), a setting of 1050 works much better for me.
'77 S with '78 930 power and a few other things.
