Installing new air intake tube.

i put in a new 3" intake tube, you know the home depot kind, and re-attatched the bov to the back of the apexi intake. i left the two other vacuum lines open, but the metal sensors attatched.

problem is, the car won't idle and drives really rough. is it possible to have a line too long to the bov, or does the bov have to be perfectly level for the car to idle? it is the stock bov.

i may have put the metal sensors on the wrong lines, or backwards, i wasn't paying attention when i took them off.

i wish i had a pic, but i am at work and don't. could the tps have come out of adjustment due to this mod?
