So here's an odd one. CEL comes on with P1420 code under this condition: The fuel tank is filled, and then driven to about 3/8 of a tank. Above that, no CEL, no code comes in.
Just purchased the car from a fellow enthusiast, and he changed out a purge valve. That said, the circumstances above are quite odd - what would the fuel tank level have to do with the alarm coming in?
Suspect things to pursue:
In the meantime, I'm going to clear the code at 1/4 tank and drive it around a bit to see if it comes in again, or if it only comes in on the transition from full to about 3/8.

Suspect things to pursue:
- still the purge valve just because? But that's an expensive Easter Egg troubleshooting method
- gas cap? Not sure what level has to do with it, but at least it's a cheap Easter Egg.
- random vacuum leak? But again, why would this be tank level dependent?
