2021 Chevrolet Silverado 1500 LTZ 6.2 — anyone else: Air down for trails but still drive pavement between sections

I'd want a measurement, not a hunch. Move a coil or plug on the 2021 Chevrolet Silverado 1500 if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. A shop burned me once by skipping that step. Not trying to scare you — just skip the expensive first guess. I already checked the easy fluid levels.

Start with the test that can prove you wrong. Two 2021 Chevrolet Silverado 1500s can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. Had a similar mess a couple years ago and that's what finally sorted it. No warning lights, which is why I'm documenting it.
