Solved!? 700

Frick'n O/2 sensor...unhooked it. All vacuum readings returned to normal as did all other operations. Idles smooth as glass (I am sure it's running a tad rich in this mode). Check engine light on of course. Will drive a couple days with it unhooked to see if problem repeats or not.

Why the hell are the no test values about Regina o2 sensors anywhere? (read: not blaming us on the BB, just NGK and the internet in general). At least a cold value and hot (warmed up) value would be nice so you could test the range and see if you are close.

Thanks for all who helped guess at this. You helped eliminate things that were not broken so I could narrow this down! I'll repost if this is the REAL fix or not. When and if I get a new sensor, post some readings and temps to help others.

Go Bricks!
Barry
