Ok, now that i got my car started and running (sort of) I haven't connected all of the vacuum lines, primarily because I can't remember where they go back. If anyone can tell me what vacuum lines go where for the upper intake or post a diagram, it would be much appreciated. Thanks.

 

I have a diagram for a 1995 but the labels are not read able, and i doubt they are the same for 91.

If some one says it is, i will try and post it later.


EDIT:
found these for you

no one has a diagram? Well I have all the lines conncected except for one which I have no idea where it goes to. Its the one vacuum line that has the black wire protecting stuff around it

 

What about posting pictures?

might be able to help better that way.

 

I also found that same one. The vaccum line comes off the thermactor air divertor/ air bypass, im not sure which is which. I belive it comes off of the solonoid that is closer to the ground.
