So I've been working on a low vacuum issue, and I just read that the P port on the TB is supposed to have vacuum at idle - but mine doesn't. My boost gauge used to be hooked up there, and it would see vacuum and boost while driving, but nothing at idle. (I moved it to another source because of this)
I've read maaany people saying it should see vacuum at idle - including at least 1 "Wiseman."
I've read that it can be clogged, but if I can see vacuum and boost while driving, I wouldn't think that's the case....
Anyone know what the deal could be here? It might be completely unrelated to my low vacuum issue, but it just concerned me.
Edit to add: Just found this guy (http://chicago3s.proboards.com/thread/146/1g-mods-free) saying that the P port only sees vacuum on 90-92's....
