Strange Sound on Deceleration

[CaSp3r9]

Homer - makes sense as it does kind of have an electrical solenoid-type sound to it.

If anyone else has a chance to get their car up on a lift and see if they have any sort of play in their wastegate linkage as well I'd appreciate it.

I'm not sure check valve was the right term. More of a pressure relief valve. Anyway, the sound disappears at around 1750 rpm, which I assume is when the injectors come back on before the engine gets close to idle.
As smooth as this 4cyl is, I doubt its the wastegate rod rattling.
