I'm not sure if this is the correct place to post...

I just got my 8, and Im just trying to fix all that the previous owner messed up or neglected.
To start I need to figure out where this vacume line or hose goes...it's also causing the CEL to come on

It's hard to explain since I'm still a noob... But here are done pictures showing the hose/line





My best explanation:
There's a hose going into they cylinder looking thing, the a metal line coming out with a PVC type 3 way... Then this line is just hanging in there. Any help appreciated

 

thats the actuator to the VFAD which is more than likely not even installed anymore since you have the AEM intake. Cap it off or remove it.

 

That end doesn't matter....as long as the nipple in the UIM is blocked off that part is not connected to anything ( it is under the manifold behind the throttle body)

 

Have you had your code read? Why do you think that this hose is causing the cel? As mentioned above this hose has no place anymore since you have an AEM intake.

 

Yea when I got it checked the guy at autozone said vacume leak or dirty air filter

When i looked at the intake filter it had the aem back on it ( wasn't sure if its suppose to be there, didn't make sense to me so took it off)

I guess I'll cap it then reset the ecu and see if it comes back on or not... Ifit does ill get the code and post it here

And is it bad if I reset the ecu too often? I did it twice already (the pressing brake pedal and pressing the trip button AND disconnecting battery...I did all three)

 

Okay got the cel checked the codes are

P2096
P0171

Autozone said major vacume leak or mad sensor
Basically lean airfuel ratio to bank one

Also the car lost control the other day and got on a curb,
One tire was out so I just got a temp tire for now until the shop gets kumhos in stock, but the temp is of more profile, will that cause the
ABS, brake and traction(yellow car with skid marks) to come on or did I damage something else?
