I tested vacuum with a proper gauge. At idle, it reads steady at 16"Hg. Snap test: it drops to almost 0 then raises to just a hair past 20"Hg.
I tested MAP voltage at idle. It reads 1.6 VDC but moves around a little........like 1.64 to 1.7. I couldn't get the test leads to stay put to snap the throttle (and I didn't have a helper).
