3.8l 25k MILES makes weird pop/ hiss right when shut off

Words will not do this justice... 2009 3.8 l 25K miles. When shut off, turn key off, engine quits, then a pop/hiss kind of noise, one time... not expecting this to be solves, just wondering if anyone has heard this behavior...
By one time I mean it does not repeat in that cycle, happens at every shutoff...

I know I'm stumped. No clue. Is there any way you can narrow down the area in the engine compartment.

It definately seems like it's coming from the throttle body, but since mine is quiet I don't know if that would be considered "normal". If it's otherwise running o'k I'm not aware of a possible inexpensive fix. Maybe someone can give a more definitive opinion on it. Maybe it just needs to be cleaned. I'm not sure and I don't want to point you in the wrong direction.

stumped

runs fine, rolling 21 mpg avg, not eating oil, no codes... stumped... I can say I don't have patience for issues and will trade it before I spend any significant amount chasing it... not married to having a jeep...
