It's strictly only when I'm deacceleration in neutral and the A/C is on anything besides low (2nd level or higher), and it's only 90% of the time. I couldn't replicate it today for example but happened the rest of the this week.

Does it have to be AC, or will it do it with the fan?
The AC compressor is intermittent with low fan because it doesn't push enough air through the evaporator to put enough heat into it. There's a thermostat in there to keep the evaporator from frosting over. This may explain the intermittent nature of the sound.
If it also does it just with the fan on high then there are other explanations. I'll stop here for now. Don't want to make it too confusing.
Can you get a clip of it?
