In that diagram the hose that says to bottom fitting has 2 fittings on my car and I was missing the bottom one and I just don't know where its supposed to go to

The bottom three squares is what the vacuum routing should look like on your car. Odds are you don't have the vacuum solenoid for the air pump anymore. Which is not an issue, just remove the splitter and plug the egr solenoid vacuum hose into the intake port.

The emissions sticker that is particular to your car is right on your radiator cover.

Thanks that's exactly what I was looking for. Now I just need to figure out if there is some other vacuum leak causing my high idle or if its the iac valve

Check for cracks in the intake elbow, check for cracks in either of the rubber hosed for the PCV system. You can also pull out your IAC and clean it.

Best thing to do is hook up a vacuum gauge to the intake and see what vacuum you are pulling.

There is a small crack in the passenger side pcv hose but that's been there since I got the car...I kinda noticed the high idle after I got it tuned but then I had him send me another tune where the idle was set to 850 and it still sits around 990

Fix the crack if you know it's there.
Does the idle sound like 990 or just look like it on the guage?
LT1 tachs aren't the most accurate. My idle is set to 750, but the tach appears to read like ~850.

Well when I'm idling at a light it seems like the car wants to still go like it feels like it wants to creep so I almost have to have the brake pedal all the way down cuz in the winter when I was in light snow I'd be sitting at a light and my back tires would still spin so I think it reads and actually is around there...to fix that hose, just get a new one?

Yeah, just some new rubber hose. You can get some at any parts store. Check your intake elbow thoroughly.

shutzero

Well the intake elbow is like brand new...what size hose should I get?

Just take the old hose in with you and get some hose to match.
Check the other side of the intake as well, the two rubber elbows that connect the metal PCV pipe to the front and side of the intake could be cracked as well.

sorry, if this is in the wrong section but, on another note for the vacuum lines, ls1 specifc, if i have a leak in the MAP sensor vaccum tube (like i accidently cracked it lol) would that casue wierd surging and stumbling when WOT'ed?

shbox

Any innaccuracy in the MAP reading is going to cause issues.
