I need to know where this vacuum line goes to. It's never been connected since I bought the car. I looked on a J-spec manifold I have and there isn't one on it, just one on the a-spec. I Think this may be the reason I have to keep my idle at 1000 for it to idle nice and smooth. My car is a 87 TII. I took this out because I removed the acv, split air, and egr. Just need to know what that vacuum line was/is for.

 

I believe that one goes straight up to the left side of the fuel rail.

 

Do you know where? There is a line going to the end of the fuel rail on the car now from the back vacuum rack.

 

looks like ......maybe its the line that runs to the oil filler neck? The other end goes to the charcoal canister. I have the diagram for emissions stuff in front of me, but its kinda hard to make out where the lined travel.

 

Well I looked at the diagram the FSM has and the line in question is not on there. Somebody must have this line hooked up on there car???




The diagram is 4B-5
