Why does a vacuum leak increase engine RPM?

If there is a leak, the cleaner will artificially enrich the air/fuel mixture. This will cause the engine RPMS to increase when the cleaner is sprayed near the source. In theory, repairing a vacuum leak is simple: you replace the leaking component.

What should the engine RPM be before starting the car?
