Default Vacuum leak near throttle body, help!

Tonight I finally turned on my 2.0 swapped GC8. Everything else is fine, but the car is dying off when I try to move the car. There is a crazy hissing sound coming from the throttle body area. I can't see where the leak is coming from. I used a brand new throttle body gasket. Are there any other vacuum leak areas on the throttle body besides the gasket?

^^^ This would be my guess for starters especially since you can almost pinpoint where the sound is coming from. That is either poorly connected or the hose needs to be replaced. Are you throwing any codes?

Or try the soapy water trick. Spray some soapy water around the bpv, those gaskets wear out from time to time..

No codes, it ended up being the AICV o-ring/gasket. Replaced it and the hissing sound is gone.
