What are common symptoms or problems associated with a vacuum leak?
One of the primary signs of a vacuum leak is sporadic idling.

What happens if you have a vacuum leak?
When a vacuum leak occurs, some air enters the intake manifold without passing through the throttle body. The ECU, meanwhile, injects the amount of fuel necessary based only on the measured air-flow. This results in a lean fuel-air mixture, which then leads to erratic idling and lacklustre low-speed performance.
