I have been troubleshooting this prob for the past week and can't seem to figure it out...I think I have checked all vacuum line ontop of and below throttle body but still I am hearing a very noticeable leak when its running , also My car will not hold idle whatsoever since this air leak started , though it does run great so long as you don't let it idle down by letting off the gas!!!!???? I AM STUMPED??????

Check the (triangular) O-Ring that seals the TB to the TB elbow

Well I figured it out!!!!!!!! If this should ever happen to anyone..Believe it or not it was the lower fuel injector plastic seal on the secondary rail towards front og car......It didn't leak fuel at all but made a very noticeable air leak sound as car was running!!!What give it away was whenever you would try to decelerate it would get even louder!!!
