Ok so I was installing my fmic today and pulled my vacuum lines on my throttle body and wasn't paying attention to where they went, now my bov isn't really blowing off and I'm hitting fuel cut at like 11psi.. I need to know how they go by the color lines on the hoses. Here is how I have it right now

The 2 on the top I have the hose with the red color lines on the left and the hose with the blue/greenish colored lines on the right.

Now in front of the throttle body I have the hose with the yellow lines on top and the plain black hose on the bottom.

What did I do wrong??

Please help, I need to get my car running before class in 40 minutes!
 
Not sure if the 90 is different, but they have the vacuum line diagram for a 1g.
