Where does this intake vacuum line go??
The plug circled in red(next to the diagnostic port), could someone PLEASE post a pic of where that connects on the other end? Thanks!

The power steering LOOKS like it goes there but if you look carfully (I checked my car as well) that line goes into the port close to the block (to the left), just above the main rad. hose. Looks like the same hose though. Unless, of course, my PS hose is connected to the wrong one

it goes to one of the two ports on the PS pressure valve, as you can see in that picture.
one port on that PS pressure valve goes to the intake manifold, the other one goes to that port right above the coolant outlet by the upper radiator hose, which leads to the intake near the air filter, IIRC.
this PS valve just creates a controlled "vacuum leak" to raise the idle up when the PS pressure goes up, so you don't bog down your engine with load from the PS pump.
