So , I can not think of anything to relate with what you just described .

I would replace the vacuum hose to the booster . Then I would use the propane trick and chase down any and all vacuum lines & devices you can find and / or get to .

I do not know if this has been asked , but have you gotten a check engine lite or service engine soon lite ?

I got the hoses ordered. Should be here in a few days. Mean while I will try your idea with the propane touch to find leaks this weekend. As for the check engine light, yes it is on but it only has one code. It's P0420. It's saying that the Catalyst efficiency is below threshold. So two weekends ago I cracked open the cat to see whats going on and I found out that the cat has been gutted. Meaning it looks like it has a cat but when I removed it the cat did not have the insides in it. Basically is just a straight thru pipe. So I ordered a cat so I can pop that in this weekend too.
