The car, not me.

I'm getting a fwapping sound, consistently about 3 fwaps per second. 90% of the time when it happens it's during deceleration. It doesn't happen during all decelerations. By decelerating I mean the car is slowing down. With or without braking, with or without downshifting. Not rpm related. All insulation has been removed and it sounds like it could be in the trunk area, maybe on driver's side. Electrical? Fairly loud. No fuel problems and is louder than a typical fuel pump but I am not familiar with Boxster mechanics yet. I also don't think it's axle rotational due to consistency. Lasts maybe 10 seconds. If I accelerate it doesn't respond. It's a very distinct sound but I haven't been around Boxsters long.

What say the hive?
