I will continue tracking today, I guess. HVAC holds vacuum when I test it, so that doesn't sound like the problem. All prehiprials seem to hold vacuum in the fuel system, as well as dist.
I'm going to test the brake master cyl. and see if that is a problem. It might just be easier to smoke it.
Is there any other vacuum lines that go crazy places that aren't obvious? It has to be a large leak, so you have me worried that there is an entire hose disconnected or something.
(I guess I could just follow the diagram.)

Mine was at the stainless EGR where it joins at the plenum.
good luck!!

Eating my words now about vacuum, went over the entire spider and found the line that manages the vacuum advance for dist. completely off the intake. I have a feeling that was all of my problems, and could extend to it leaning out and missing on acceleration, because of pre-ignition.
I would love to take it for a drive to see, but I got in the car to turn it over, and it turned over once and now won't turn over.
I love these cars. but sometimes.... haha.
Anyway, jump post to yellow wire turns over, so not starter or wires (brand new wiring harness), and I have 12v when key is in "start" at pin 87 on the relay bridge. So it must be somewhere between the two I guess. Is there any common fail points between the two?
