I also saw this build up on the bottom half of the air box. I am assuming that I oiled my k&n filter too heavily, and that some of the oil awas sucked through and coated the MAF. Cleaning these parts seemed to help the throttle response of the car. Now I just need to pinpoint the problem causing the hesitation. I'm going to take a good guess that it is something involving fuel delivery.
