throttle body
there is two pipes for vacuum lines on the bottom of the throttle body.
what are they called and where do they go?
i tried looking for the information but i can't find it. sorry for the novice question haynes just tells me to make note on all the lines when i disconnect them and i can't find the info by the search bar, and i got the car with out some things and other things going to wrong spots and bypassed to arias that make no sense.

Re: throttle body
If you are referring to the bottom of the throttle body, those are coolant lines put there by GM to keep the throttle body from freezing up. If you are talking about the big one near the top, that goes to the big plastic vacuum tree in the back of the engine. The metal tube that looks like accordion shaped is your EGR feed line that feeds exhaust gasses back into the intake stream. The only real vacuum connections are the large plastic line and the smaller plastic lines near the IAC valve that feed everything else.
