Hit 80 diagnostic scans this week and nailed every one

I was at a shop in Phoenix last Thursday and this older Ford was stumping everyone. I pulled out my old oscilloscope instead of guessing like usual and found a bad crank sensor in 10 minutes. Anyone else ever have a specific tool just click for you on a rough day?

My buddy John swore by his infrared thermometer and found a bad exhaust valve on a Subaru that way.

Used one myself on a buddy's Subaru and found a clogged cat the same way.
