Update on P0308, P2237, Posted 2340.
Had one more occurence a few days ago.
Similar initial conditions, car had been unused for 8 hours, about 15 minutes into drive, on a slight downhill, with a middle bit of acceleration (not floored, but also not 'cruise') pedal input.
Lights on dash as before (flashing engine, 4lo, !). Cylinder drops. A few seconds after that the Misfire 8 code was registered. I cleared it. The engine went back to 8 cylinders, then the O2 sensor codes followed a few seconds later, and the cylinder dropped again. Misfire was not re-registerd.
I pulled over. Turned the engine off. Reset the codes. Restarted and drove the remaining 25 mintues of my commute on 8 cylinders with no codes.
Spark plug, coils, o2 sensors are all replaced within the last oil change interval.
Running premium fuel, last few tanks are Costco brand.
I have a (probably) unrelated charcoal canister self test failure set of codes that shows up every couple days and I just clear, I won't be able to get into refitting the canister until after Christmas.
