Default Throttle body vacuum hose

I spent the past hour searching this forum and can't find the answer. To what does the other end of the throttle bottom connect? Is it the oil trap? I noticed the oil trap had a small spigot with a connection.

Thanks

I'm replacing the rest of my vacuum lines today, if not one responds by the time I am done I will look at mine and let you know.

It'd help to show a picture. The only hose in the rear hooks up to the evap system.

Typo it is the vacuum line attached to the top of the throttle body. I'm not sure where the other end attaches

Looking at the TB from the front of the car the vacuum nipple on the lower left connects to a solenoid underneath the black covered wire harness attached to the engine wall (to the right of the TB).

#12 goes to a nipple under the hose that connects to the valve cover. There should be a check valve connected to it as well (part #7 in the pic below).

I believe it does and I'm missing the check valve that goes between the two. My car is currently revving at idle. Is this correct?

Sounds like you might have the old pvc system, I would check and upgrade to pvc #6. It will help with a number of issues that can present themselves at usually the least expected times
