intake vac lines.
 

sup gents, been out of the car game for a while and so has my car, need a solid from someone to confirm how these lines should be hooked up. ive searched my ass off and found 3 different ways these lines were connected. car was turbo but had to change to stock for smog reasons. its a 2008 40th AE.

below are pics of how i had it hooked up but im having rough idle issues and gives code P0171, cleaned the maf sensor and tried to hunt down a leak but i havnt found it yet, i suspect my lines are not hooked up correctly thus giving me this code. i also have a K&N intake for the EO sticker. i know in one of the pics a hose is disconnected to the oil port and no i did not drive like that, i was just seeing if it reached the intake.

the diagram picture is the one ive seen plastered everywhere. if i hook it up per the diagram i have 2 hoses that do not connect to anything. would it be wise to buy fittings and make a tee and hook the other two hoses up?

Your pictures don't really show anything about where your individual lines run.

I see one with 3 lines ran back under the engine for some reason from the intake, but then it looks like your oil filler neck goes to the LIM nipples. SO where does the third hose from the intake go?

Also check the VFAD nipple just behind the throttle body. It's the orange line in the pic. That should have a cap on it since you don't have the stock intake.
