I understand (have no personal experience with this) that a free air BOV can cause this kind of stumble. I'm assuming the SSQV is not recirculated? Basically, MAF is telling the car there's more air than is actually getting in, causing a rich condition. Leaking FMIC piping could also be to blame.

And yes, I know I just restated you guys
