Hi guys im actually really new to this whole owing a car thing, and my first car just happens to be a 95 4runner 2 wheel, now I've gone and cleaned the rvc and the lvc and replaced their gaskets. I've cleaned out the plenum and replaced its gasket, I've even replaced all the spark plugs, but i think i am missing a vacuum line, and i have no idea what it is suppose to be. I have circled the spot i think i am missing and the place i think its connected to but I'm not sure, some help would be greatly appreciated!
(If you need better pictures or closer pictures please ask with as much detail as possible so i can get a proper picture)

 

Welcome to YotaTech.

You're going to need better pictures. The rubber hose you have circled in the front appears to the be overflow line from the coolant reservoir. It doesn't connect to anything; it just points down.

The other circle is in the "area of" the fuel pressure regulator, A/C idle-up supply, and the PAIR supply. But I sure can't tell from the picture.

 

We were sure the one on the bottom right was suppose to connect to something, now i know what it is, thank you. As for the other one here is a better picture i hope

 

Metered ("after the VAF") air from the air cleaner, that goes to the right side of the plenum, and provides input air for the A/C idle-up. Do you have A/C? I don't know enough about such trucks, but it would not surprise me that the part that goes under the plenum would stay the same, with the port on the air cleaner (and at the other end, the plenum itself) plugged.

 

 

Yes we have A/C in the truck the engine seems to die if the truck idles for about 5 minutes with the A/C on. I will see if i can locate that line, unfortunately my aunt was taking the truck apart while i was at work so i didn't see this piece come off, so i didn't know what i was looking for. But now i do thank you very much!
