To fix a check engine light caused by a vacuum leak in a 2004 Impala SS, first, visually inspect all vacuum hoses and connections for cracks, breaks, or disconnections. Use a smoke machine or carburetor cleaner around suspected areas to identify the leak—if the engine idle changes, you've found the leak. Replace any damaged hoses or fittings, then clear the check engine light using an OBD-II scanner. Finally, take the vehicle for a test drive to ensure the issue is resolved and the light does not reappear.
