[killmeS13]

The car wont idle under these conditions (involving IACV):
-MAF in, IACV in
-MAF in IACV out
It will however idle with:
-MAF out IACV in
-MAF out IACV out

The IACV shows .15v with key in on position and ground shows continuity.

I have checked all vacuum leaks to the best of my ability and have come up empty-handed. BOV is functional, no air noises coming from it, and its brand new.

ECU threw two codes at me
The first time around I got a 55 the second time I got a 12

I'd again like to add, I got that code 12 using a known good MAF that runs my other SR perfectly fine.
