After I shut off my engine in my 2000 Grand Prix GTP, I hear some sort of gas leaking. At first it sounded like air still being sucked into my CAI, but now I believe it's a leak in the A/C. I cannot tell where it is coming from.

Video would help if possible. And you mean it sounds like someone letting air out of a tire?

Mine does that too. I only notice when my hood is open tho. I believe it's coming from the brake booster?

If you don't use the AC, you probably don't hear the noise..
That's normal, it's the pressure etc n the AC system doing it's normal thing.

Okay, because it only happens if I have the A/C on, and I'm scared that it is letting out freon. I had to recharge it this spring, so hopefully nothing is leaking.

The ac is a closed system, so if you had to recharge, you had a leak. Most r134a's out there have a leak sealer in them though, so it's possibly fixed for now. I doubt that's your noise though, if it was leaking fast enough to be heard it would be empty over night

I never use my ac. Honestly cant remember that last time I did haha So is that still what it is?

My A/C still blows ice cold and the noise still happens when I turn the vehicle off, so it should be good

its your ac refrigerant leaking through your orifice tube from the high pressure side to the low pressure side. Its normal.

Ricky..that elbow from the hose into the booster is a check valve...you may want to check it.
