Hello, vacuum leaks would cause a lean running code, not a rich one. You would be looking for an air restriction - not abundant air. Or, too much fuel being delivered without being commanded, such as a stuck open fuel injector. It's definitely a concern that must be resolved - so it might be that some hands on professional testing is warranted.
