I've been searching around for a vacuum leak after I got a CEL with the 1126 code and I'm almost positive it's coming from the middle of the oil fill tube under the center section of the intake system. I can hear some hissing at idle and when I press down gently on the exposed part of the oil fill tube as it disappears under the intake the hissing sound gets louder and the motor starts running rough.

So if there's a DIY someplace with a bunch of pictures I could sure use the help.
