The lean air fuel condition is picked up by the exhaust oxygen sensors who, in turn, report this to the computer.
What does a bad vacuum leak sound like?
Hissing Sound
This is a common symptom of a vacuum leak in a car.

This, too, is caused by the fuel starvation that is going on inside the engine because there is too much air leaking out of the vacuum hoses.
Can a vacuum leak cause misfire?
Vacuum leaks, especially those that are confined to one cylinder, will cause the engine to idle unevenly and possibly misfire. This is because the vacuum leak allows additional air to reach the affected cylinder, diluting its air/fuel mixture.
