About 5 seconds later, the CEL went away and everything was back to normal. Has anyone else experienced this, and is there a confirmed fix?

Car is a stock late-2013 with 42k miles. It had the spring recall done at like 10k, several years ago. It has an injen evolution sealed cold air intake and muffler delete. Code wasn’t current, but it was a multicyl random misfire. FF data looked okay, air mass and IATs were both on the low side of normal for the conditions. The intake has never caused me any issues on my LTFTs either.

The rest of the drive was completely fine. Driving around the valley (1500-3000 feet) was also completely fine. I’ve experienced a loss in power at high altitudes in basically every car I’ve ever driven, but never had a misfire except during sudden changes in throttle input.

Y yes, jest don't do that no more -

Seriously, I reckon the engine just hiccupped, I wouldn't worry about it.
