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.

Chapter Markers & Highlights

00:00 – Monologue: The Relationship & The Process

• Story of an ’06 Acura with years of failed repairs.

• Point: diagnostics require commitment (“go the distance”), not poking and hoping.

12:05 – Micah in Maine: Subaru Legacy

• Example of a strong shop–customer relationship.

• Rustproofing mishap solved because both shop and supplier worked together.

• Lesson: trust and respect pay off.

17:45 – Rocky in Maine: ’92 Jeep Wrangler

• Rear main seal leaking after clutch job.

• No miracle fixes; check PCV/blowby.

• Seal job takes finesse; plan proper repair when practical.

24:45 – Ted in Illinois: ’17 Chevy Silverado

• RF brake drags after driving.

• Internal hose failure can act like a check valve—sometimes on the other side.

• At ~100k miles, replace both front hoses and bleed system.

31:00 – Jacob: ’11 Buick Enclave

• Replaced injectors, pumps, cats removed, still bogging/misfiring.

• Lesson: stop the parts cannon.

• Next steps: restore cats, check manifold vacuum, test injectors properly.
