2018 Chevrolet Tahoe — check-engine light turned itself off — still scan it?

Intermittent stuff lies if you only catch it once. Move a coil or plug on the 2018 Chevrolet Tahoe if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. On “check-engine light turned itself off — still,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. Video is ugly but it shows the hesitation.
