This is accomplished by using a methodical, scientific approach to accurately confirm a diagnosis before attempting a repair. Subscribe here and you’ll stop firing the “parts cannon” by changing O2 sensors, plugs, and wires to try and fix your check engine light and instead use professional-level advanced Auto diagnostics and repair with tools and equipment available to any home mechanic.
