Final answer:

To diagnose vacuum leaks in an engine, methods such as injecting smoke and listening for leaks are used.


Explanation:

Vacuum leaks in an engine can be diagnosed through various methods. Injecting smoke into the intake at idle is a common technique to detect leaks, as the smoke will escape from any leaks present. While they can affect engine performance significantly at idle, engine RPMs increasing upon ingesting artificial enrichment is a sign of a separate issue. Additionally, listening for a leak can sometimes help in diagnosing the problem.
