I made a vacuum leak on the lower intake manifold by not sealing the ACV block off plate completely. This is a pretty universal sound of a vacuum leak on a rotory engine. The severity of the leak in the video was very minor, it would create a sound of misfiring at idle, also the car would die once it reached operating temperature. Most vacuum leaks on rotorys are incapacitating, but this was very small in order to show others what it sounds like
