Where would you look for a vacuum leak on a 2001 Olds Alero?

To locate a vacuum leak on a 2001 Olds Alero, check common areas such as the intake manifold gasket, vacuum hoses, and throttle body gasket for cracks or disconnections. Inspect the vacuum lines for wear, brittle spots, or loose connections. Additionally, you can use a smoke test to identify leaks, or spray carburetor cleaner around suspected areas while the engine is running; a change in RPM indicates a leak.
