I just rebuilt the engine in my '91 bird. 3.1L. It Had 300,xxx miles on it and a freeze plug started leaking so i thought, hey, good time to rebuild.
Before and during deconstruction / removal I took pictures of everything, in case i forgot how to put something back together. Unfortunately, soon after getting the engine completely torn down, my hard drive died. So I lost all the pics. It was no prob putting the engine back together or putting it in car, but now im down to re-attaching vacuum lines...and am lost. I looked in my Haynes book, but it was absolutely no help, I searched forums, again no help. Does anyone have a diagram or picture maybe that would help me? The place im having the trouble is with the lines at the rear of the intake. I'll try to attach a pic.

Ok, heres the prob area. I know whats hooked together prolly isnt right....and i seem to have an extra nipple....

Your engine should be here.

Ok, maybe im just not seeing something in their diagram....but i cannot find where its showing the lines or connections that im talking about.

there could be one that is there but just capped from the factory. ya somethin for like ca emmissions. get what I mean?

nah, im sure it was hooked up before. Doesnt anyone here have a 3.1 they can take a picture of, at the back of the intake, by the distributor?

Ok Im at work so I cant give you any pics...but ill try to explain it... There should be a module bolted almost right above your coil...It hooks from the back of the intake to the underside of that module. It should be bolted to the lip right below the cowl area. Hope that helps.

Hot damn that's it!!! Thanks alot man, its been driving me crazy.
