Not sure how this works with a PowerFC, but I assume you still get CEL's

I had hunting issues with my car, turns out to be the butterfly adjustment screw on top of the manifold, the threads were worn and it had a tendency to vibrate outwards, allowing more air in to the point where the IACV couldn't do its job; as there was simply too much air to cope with.

Rectified it by dribbling some loctite on the threads of this adjustment screw, and tinkered with it until I got the desired idle speed.

Might be irrelevant and you might have the non-divorced IACV type (unlike mine)
