Hey whatsup everyone. I was just needing some help with this topic. I figured this the best place to get the info I need. I am just trying to find out where the vacuum lines for a 3.1L go. Theres three lines behind the throttle body and two lines behind the plenum. If someone could just tell me where each one goes, and if it splits into a T or if its just straight from here to there. Also if you could say if its like the line on the drivers side or the passenger side, so I don't hook up anything wrong. A vacuum diagram would be nice also. My hood was replaced before I got the car and is missing the diagram. Thanks for any help on this.

 

1. this is a double post.
2. the last topic you posted this question in had the answer IN IT if you would have read it.

 

I did read my previous post thank you. On that one though, it says there are two lines coming out of the throttle body, but isn't there three of them. I just wanna know man.

 

The throttle body should have a rubber plug that goes into it with what looks like 3 holes, 2 are vacuum lines, the other is just a plug. I don't remember where they go.

 

the thing is I gave where they went in the other tread.

 

Actually, it's a triple post. rsttop, did you ever follow up on the help that Rbob gave you back in March 2004? Your old message is here: https://www.thirdgen.org/techbb2/sho...postid=1746003

Personally tho I can't stand that GM didn't put the vacuum diagrams inside the GM service manual!! They always say "look at the hood sticker"- I haven't had a hood sticker since 1995. (sigh)
