I'll be attacking the iacv today, might make a video out of it for the blog (I'll make one of the symptoms and duty cycle as well). I imagine that if the fuel pumps were the issue that it would bog down in higher rpm but I could be wrong. They definitely spin up and are audibly on when you peek under the back of the car, no real deviation in noise but I can add it to the list after ruling out the coil and ignition module.
