That injector seal leak on a 6.7 Powerstroke had me chasing my tail for three days...
I was sure it was a bad injector, so I swapped two of them before I finally pressure tested the fuel rail. Turns out the copper washer on the number three had a tiny crack you could only see with a magnifying glass. Anyone else ever get fooled by something that small?

Oh man, that's the worst! I spent a whole weekend on my old Duramax convinced it was an injector solenoid. The problem was just a single, frayed wire strand in the harness. Couldn't even see it until I wiggled it with the key on.

My buddy's F-250 had a rough idle that felt exactly like a bad coil pack. We replaced three of them before I noticed a single plug wire with a tiny slice in the boot, maybe an eighth of an inch long. It was hidden under a bracket. @anthonyp91 knows the pain, it's always that one stupid little thing you overlook because the symptoms point to something bigger and more expensive. You get so focused on the hard parts that the simple fixes blindside you.

Ugh, those tiny failures are the absolute worst to track down. @anthonyp91 is right, it's crazy how one little thing can waste so much time. I had a similar fight with a coolant leak on my truck that was just a pinhole in a heater hose. You look at the big stuff forever before finding the real culprit. Makes you want to pull your hair out, doesn't it?
