About the channel
Schrodinger’s Box is widely recognized as one of the best DIY auto repair and diagnostics channels on YouTube. This channel is for Advanced DIY auto repair with focus on preventing "parts changing"- that is- changing parts on a guess because of a lack of understanding on how to test if a part is actually faulty. This is accomplished by using a methodical, scientific approach to accurately confirm a diagnosis before attempting a repair. Subscribe here and you'll stop changing O2 sensors every time you get a check engine light or waste money changing plugs and wires to try and fix a misfire. Find exactly what is causing the problem and fix it right the first time with confidence!
