AEM CAI error??
One thing to check is the VFAD line coming of the intake manifold. If it is not properly capped, you will get a CEL at high RPM, and it will stay on for a while, then will come back on when you go to high RPM's (if it isn't capped right, you will hear a loud hissing noise.)
Check out my attachments.
(It is the orange line in the 2nd picture)
the only thing to take in mind here is that if you DO get the MS intake over the Aem, and have them install it, they will cover your warranty with the intake because its a "green" warranty item and certified by them
