Vacuum Line on Intake Manifold?

[habitatguy187]

Alright I've been having a bad idle/kinda like fuel cut problem for awhile now and recently I started trying to track down all the vacuum ports, because when I first bought my car some guy pulled off all my vacuum hoses and told me I didn't need to cap any of them off. So I think I've found most of them now, but my hg and idle is -16, and I still get a "something like fuel cut" problem in the 5k area.

My question is, are there any vacuum ports on the intake manifold? I've tried to look but couldn't find any, yet i've heard that they're there. And please don't send me the taboo speed shop diagram as I can't make out any from it.

If you have a picture of where they are (if they're even there) that'd be great. Thanks.

BTW I've done BLT after BLT with soapy water and fixed all the problems I found, yet there's still something wrong.

A BLT will make them obvious.

Here's a picture of a 1g intake manifold. There's 2 vacuum ports on the front - one near funner #4 (for PCV) and one near runner #2 (for bov). There will also be a port for the FPS as well as the brake booster. I believe that is all that runs to the manifold.

Boost leak test + spray bottle of soapy water.
