can't pull brake vacuum
 

Just looking for some thoughts on where to start looking. :icon_tinykitball:


Engine runs, a little rough but runs.
Brake booster line is unplugged from top of manifold(obviously why it's rough)
If I hook it back up (or plug it with my finger) it dies

Slight update. I did find that when hooking up the booster, there was a 1k rpm drop.
That's why it wouldn't stay running.


As a quick fix, I adjusted the idle up to 1500 and re-hooked the vacuum line. So everything appears normal.


I still have no idea what caused the issue.
