Found my vacuum leak !!! Now what
Wellll finally god fed up .. pulled the hood off and started looking around the back and pinpointed my vacuum leak ... so now how do I go about fixing it and what do I need to take off to do it? It's not a hose but this thing (i think it has something to do with power steering?)
If you are looking at the car from the front ... then the leak is coming from the right side ... on the bottom.

It's the Air Supply Valve, it's main purpose is to compensate during steering or other loads to maintain a stable idle.
I've circled it on a pic of my UIM:
Your best best would be to remove the UIM and take it off, scrape off the old gasket and put it on with a new gasket or rtv sealant. Once your under there you can do a bunch of other maintenance as well if you wanted to.

It's the air supply valve/solenoid, for additional air when the pwr steering is turned.
It's held with just two 10mm nuts. How long could it possibly take to remove it? Three minutes? Two and a half? Less time than it took to write this.

You can buy gasket paper at the auto store. A buck maybe. Then cut out a gasket using a utility knife or exacto knife.
Wanna block it off. Cut out a piece from the gasket paper to match the shape of the air supply valve and install it with no holes in the gasket. Simple blockoff. You can do the same with the EGR. Just install a gasket with no holes in it. Blocked off.
Don't like that? Get some five minute epoxy and knead it in the holes on the manifold and let it set up for a hour or so. Works fine. Put the solenoid on the shelf for later possible use.
Lack of the solenoid allows one to get his hand behind the throttle body and remove/reinstall the vacuum hoses easier.
The air supply valve works. You turn the steering. The ECU gets a signal you turned the steering wheel. The ECU puts a gnd on the solenoid and the solenoid opens and in turn ups the engine rpms. There should always be 12vdc on one wire of the solenoid if the key is to ON or better. Usually a black/white wire. The other wire is the gnd signal.
