Without looking, I'd say to the vacuum reservoir ball.

you mean the one that comes out the back of the tbi? here you go.

looking at front of tbi.

left on tbi goes back around to the little electrical thing that has 2 vacuum lines on it(egr controller). it goes on the far left one. the inside one, goes to the metal disk(egr valve)

rear goes to far left near the firewall( on my car there is a green clip on the electrical plug next to where the vacuum hose hooks up.(map sensor) dont know if thats standard color.

big one = pcv valve on drivers side valve cover.

one below big one in middle goes to cruise.

right = plugged with vacuum cap.

Still lost, I meant the one that is next to the EGR, right behind the fuel line but not on the TB. It has a nipple that bolts into the manifold.. I'm just not sure where its supposed to go...

Ok, I think I found the problem..

Where does the vacuum line that is right between the 2 fuel lines on the throttle body go to?

I don't have that connected and I think thats the problem...

the one coming out the back of the tbi between the fuel lines goes to your map sensor.

Ok that got it.. Now the car runs fine except it shifts at 2000 rpms and it won't automatically downshift even when I stomp on it..

I think i need to adjust the TV cable...

Thanks to everyone who helped.. I got the car running in top shape now.

I would actually recommend the Edelbrock TBI manifold now.. Except I had to have the bracket that comes off the compressor(or whatever that is) Drilled and tapped. Edelbrock says that it was made for trucks so they stopped drilling that hole.. whatever..


Thanks once again!
