Unhooked Vacuum Lines (Pics)

Can someone show me what plugs into these? The second one is hard to see, but it is a small plastic piece that comes from the bottom of the throttle body.

Re: Unhooked Vacuum Lines (Pics)

I replied in one of your earlier posts about your car stalling and mentioned that you are going through a lot of what I just got over. Go to a trusted shop and have them rewire your vacuum system, it's not that spendy (I paid a few hundred) and they make sure everything is correct and use new materials. After my rebuild, I learned how touchy the vacuums are on these cars and it's very important that the vacuum is 100% correct before you try and diagnose any other problems.

Bottom of the throttle body should go to a T, which one line goes to the charcoal canister, the other under the plenum and to the EGR solenoid ( your first pic ) the other line from the EGR Solenoid goes to the EGR.

First pic is EGR Solenoid, one line to the front of the plenum (under on driver side) and the other connection goes to the egr on the middle of the intake..

The second pic is the heater valve, thats vacuum hose goes into the firewall.. For closing and opening for the hotwater to the heater/AC..

Re: Unhooked Vacuum Lines (Pics)

I am trying to figure this out also, looking at the egr solenoid, if you look on the right hand side of it, you see a little metal clip on the solenoid. what plugs into that?
