springram is on a distinguished road

Not exactly the same, but at 1,760 miles the CEL came on. I had no choice but to continue driving to my destination. Stopped by Autozone, as it was Saturday evening, and they found code P2099- "Downstream fuel trip system 2
rich/ECM has detected a fault with the downstream O2 sensor"
Oddly, when I restarted the truck (4th restart since initial CEL) the CEL was gone. I went back and verified that he didn't clear it, which he had not. This was at 1,890 miles.
Dealer said if it went away on it's own, it's probably fine, a glitch. Not super comfortable with that. It has not returned and I'm at 2,500 miles now. MPG appears to be what it should.
