Wasted $600 on a fancy diagnostic scanner that just told me the same thing my ears already knew
Bought a high-end Autel scanner thinking it would crack the code on a weird misfire, and after three hours of scrolling through menus it basically confirmed what I'd guessed from the sound of the injector clatter, so now I'm wondering if I should just stick with my stethoscope and gut feelings or if there's an actual tool under $200 that's saved your bacon on intermittent electrical gremlins?
Man I feel your pain on that $600 Autel. Spent almost the same on a Snap-On scanner only to have it tell me what my butt dyno already felt.
The real game changer under $200 for me was a cheap power probe and a multimeter with a min/max capture function.
Found more intermittent issues watching voltage drops and resistance spikes than any scanner ever showed me.
