Sound like sooooooo after engine shut off.

I've noticed a strange sound like "sooooooooooooooo (like gas or vacuum leaks) from the throttle body area after parking the car at home and the engine off, open the bonnet and that strange sound came out like TB region, the noise was loud at first (not much I listen to it, only if my ear is closed to it) then gradually come down, I then turn off the CNG cylinder directly, but the sound was always coming. I checked the lines with air, but no leakage was apparently found, seems to leak in TB,

Experts Please help me.

take your car on a drive and DO NOT use a/c...
then turn of the engine and listen...
if there is no sound then your a/c gas is leaked...
btw hows the cooling of your ac???
