Diagnostics Isn’t a Guess: Go the Distance
Ron opens with the truth about diagnostics: commitment, not guessing, gets cars fixed. A stubborn ’06 Acura misfire sets the stage, then real calls highlight trust, process, and the dangers of shortcuts—from a Subaru owner who celebrates his shop, to a Jeep with a rear main leak, a Silverado with a dragging brake, and a Buick Enclave that turned into a parts-cannon case study.
