95 camaro 3.4 sucking air from a/c vents & loss of power cant find vacume leak


Not sure what you mean by loss of power. If you mean lack of acceleration or bogging down, than a bad cat convertor can cause this problem because you are lossing vacuum during acceleration causing the vents to switch from floor to defrost. Hope this helps leave comment.
