You guys are probably gettng sick on me by now lol. Well when i was taking the top of my engine apart I discounted all the plugs a labeled them all including the vacuum lines. I dropped one tho behind the engine, i figured i'd just get i when the heads off. Do you think i could find that f*cker! So my question is what three things pull vacuum from the three hole plug on the back of the intake? I searched an come up with Fuel Reg., EGR Valve, and Cruise. 1. my cars a 96 so theres no Fuel reg on the rail. so thats out. 2. I dont have cruise on my car. 3. I deleted the EGR valve. So far i found out one is for the EGR and the other line goes down the pass. side under the pass headlight. What is that? What is the third one? Yes all three of them was used before i took the car apart.

That line is for your evap system. It helps your fuel system breathe and expell excess fumes. That line usually goes to the inlet on top of your throttle body.

ok well i have that one. but the one on the back of the intake manifold runs goes from a rubber line to a metal line down inbetween/top the valve cover and cam gear sheild ands then down under the pass headlight.

If you mean that it runs between your timing components and your strut tower then it is your Evap.

It should run under your power steering fluid resevoir and through to a cannister behind your passenger headlight.

Look at the stickers on your hood. One is a vacuum line routing map....that should solve your question.

Really? theres no stickers under my hood? Probably because the car was wrecked before i got it and the hood was replaced. Do you guys have a pic of that sticker??

lol well that doesnt help you much. Yes there is a sticker that is a diagram of all your vaccuum lines. All cars have them.

Check the Chiltons....it might have the same diagram, look in the emissions section. I dont have a pict of it sorry.

IDK if this would help you. I took a pic of my 96 hood;



It was hard to see so I took a big pic.

thank you that helped alot. I just wrote on the picutre cuz it was easier so:

Vac resevoir is the Cruise control box under the intake. One line goes to that box and the second line in that box goes to the cruise control solinoid.

Alright cool so pretty much im gonna be safe to just block off the 2 ports that arn't being used.

Yes if your not going to reconnect the EVA in the fender well and the cruise, you can just block them off.
