My 2010 MDX very occasionally makes a hiss or rattling sound that usually coincides with pressing the accelerator and is very infrequent and inconsistent. It doesn't affect the operation of the car and I usually here it within the first half mile or so driving and just occasionally after that. Initially, I though a branch or something might have been caught under the car and making the noise dragging along the road. I also went under the car to see if something is loose. Nothing apparent.

I did notice a hose that is not connected to something and am wondering if that can be related to the problem (see picture attached).

Otherwise I am wondering how the accelerator works and what it's attached to since it does seem to coincide with pressing the accelerator and am thinking some how that is resulting in the noise. It is not related to turning or stopping.

Any help would be appreciated.

Thanks, Bill
