Why do people like to speculate what it could be. For $100, you can get a scanner to point you in the right direction. If this is a $500 beater, I understand. On a car this much? Instead, people spend time speculating what might cause it base on conditions, etc.

I have a scanner now for sure. Hope I don’t ever have to use it again. Whatever code I had last time P something. I hope I never see it again. Your think I’d remember but I’m blocking that code out of my mind.

We didn't even speculate at that time about what caused the light, just kept driving.
Because:
The car never hiccupped, all the gauges showed normal, and the light went out after a few seconds.
We were on a road trip hundreds of miles from home and no convenient dealership, especially on the weekend it happened.
And we have a 0 deductible extended warranty if something went bad.

Without the ability to work on the car at that point, knowing the code wasn't going to help us much. The dealership checked it after we got home and said all ok.
We have now owned four modern Corvettes over 20 years/250k miles. Every one of them has had occasional weird electronic glitches that fixed themselves in a few minutes. We pay attention, but we don't get excited too quickly.

I prefer to know what the issue is because it is pretty easy to. I never trust what I can feel in the butt. I have seen genuine problems with cars that the gauge does not show. The data does though. Autozone, Advance Auto, etc will scan codes for free. I also have my own scanner with me. When it tells me all is clear, it is clear. I like to do the research first, if possible before the mechanic does. I don't trust unknown people to be truthful and knowledgeable.

Not that it matters at this point, but my CEL (P0324 - knock sensor) seems to have resolved itself over the course of the last 100mi or so. Had to have been the Techron that threw things off.

Adding a bottle to a nearly empty tank might have left it with a bit of a rich mixture before it had time to slosh around and dilute after filling up (??) ... that's the only thing I can come up with.

Isn't knocking more of a lean mixture thing?

That's what I always thought ... but I've had the car out a couple times since and no issues. Techron was the only variant that changed.

That could be just the wiring having issues or the sensor may glitching.
