vac lines

I was being a smart ***. The answer is there are no vacuum lines on the intercooler but you have two small air supply lines there doing what the 88 above said.
The air supply valve is on the back of the throttle body with a large nipple sticking up in the air and there should be a hose b/t there and the rear nipple on the intercooler.
The nipple sitcking out to the right side of the intercooler goes to the Air Bypass Solenoid Valve bolted to the top of the upper intake just to the right of the intercooler. Page 4B3 of the online FSM shows it.........kinda. Air Bypass Solenoid supplys air to the BAC for the first seventeen seconds upon startup when the engine is cold. There after it does nothing useful at all. Page 4B-5 shows it a bit better.

Hmmm. It's been a while. I removed my air supply valve yrs ago on all my cars and plugged the intercooler.
I'll try to find a picture. I remember one on this forum somewhere. Later.
EDIT: Its the nipple in the jpg attached and that nipple is fed by the valve I pointed a red arrow at. Oops. Got that wrong. The nipple feeds the valve.
