To detect a vacuum leak in a 1993 Chevy Tracker, start by visually inspecting all vacuum hoses for cracks, disconnections, or wear. You can use a smoke test, where smoke is introduced into the intake system, allowing you to see where it escapes.

Lastly, using a propane torch or carburetor cleaner around suspected areas can help identify leaks by observing changes in engine RPM.
