Unpopular opinion: I swore by feeling out engine problems until a sneaky misfire made me buy a scan tool (and I'm not going back).
I always said good mechanics don't need computers, but that one tricky case showed me tech can spot what ears and hands miss, so what's your take on old-school versus new-school diagnostics?

Ignition coils don't actually crack on the outside, they just fail internally. That's exactly why a scan tool is so clutch, it finds the electrical fault your eyes can't see. The old ways are good for some stuff, but modern problems need modern tools.

On my 2015 Civic, a check engine light for a misfire stumped me. I tried listening for knocks and feeling for vibrations, but it was too random. A cheap scan tool pulled codes that pointed to cylinder 3, and it was a cracked ignition coil. That experience taught me that even the best ears can't hear computer data, so how do you balance hands-on checks with modern tools?

Man, that's so relatable lol. I've had similar moments where I spent hours trying to hear a misfire only to find out it was something the computer caught instantly. It really makes you wonder how much we should rely on tools versus our own senses. So, what's your go-to move now when a check engine light comes on? Do you jump straight to the scanner, or do you still give the old listen-and-feel a shot first? I'm curious if that experience changed your whole approach or if it's case-by-case.
