The old way vs. the new way on diagnosing injector knock
Honestly, for years I'd just use a stethoscope and pull injector lines one by one on a running engine to find a bad injector. It was loud, messy, and you'd get soaked in fuel. About 3 years ago, the shop got a laptop with diagnostic software that can read cylinder contribution and injector correction values. Ngl, it was a game changer. Now I can usually pinpoint the problem cylinder in under 10 minutes without even getting my hands dirty. But some of the older guys here say you lose the 'feel' for the engine by just staring at a screen. What's your take, do you still do the line pull method or have you switched over to scan data full time?

Oh man, that line pull method was such a mess!

My third attempt looked like modern art.

Modern art" is a bit dramatic, right?
