Showerthought: I fought against electronic diagnostics for years, and it was a huge mistake
I was the guy who'd laugh at anyone pulling out a laptop for a simple glow plug issue, insisting you could hear the problem if you just listened. Then I spent three days chasing a phantom misfire on a Duramax that turned out to be a single injector balance rate slightly off spec, something no stethoscope could catch. It cost me a customer and a ton of time, all because I was too proud to plug in the dang computer earlier. Now, I start with the scanner for anything electronic, and my diagnostic time has halved. Funny how stubbornness can blind you to the tools right in front of your face.

My buddy swore he could torque head bolts by feel until one stretched and cost him a whole engine rebuild.

Ever been so convinced you're right that you'll ignore the obvious solution staring you in the face? I once tore apart an entire fuel system on a hunch, swearing it was the pump. Plugged in the scanner as a last resort and found a single faulty sensor. Felt like a proper fool, but hey, at least I got a workout. Now I joke that my scanner is my best mechanic, and I'm just the guy who turns the wrenches. Stubbornness might be free, but it sure ain't cheap when you're buying your own time back.

How did you finally break through that mental block after the customer left? I had a similar wake-up call with my own truck, refusing to use a code reader for a check engine light that turned out to be a failed sensor. Spent hours swapping parts blindly before caving and plugging in a basic scanner. Now I make it a RULE to check the computer first, even for things that seem obvious. That shift in mindset saved me so much frustration and actually made repairs fun again. Stubbornness really is the enemy of efficiency, huh?
