I've had the issue a couple times, with both the OEM and AA X-pipe, particularly on colder mornings. I'm assuming, and someone with more knowledge can correct me if I'm wrong, that is has to do with the cold start up, and the O2 sensors continuously trying to hit and alter what is a rich AF ratio.

Had the dealership check my ICV and all is well apparently (only 8000km's/5000miles).
Probably the best answer so far. I complained to my SA about this and he told me everyone jumps too quickly to the icv fault. He confirmed what u posted above to me o2 sensors and cold start adjusting . Even if it was icv they wouldn't touch it until u get a code thrown
