Hello, Anything can cause a misfire code, fuel, spark, compression. P0300 is usually a problem that is common to all cylinders. The other misfire codes you listed were individual cylinders, driver side bank.
The last one was bank1 sensor1, 02 sensor high voltage--rich. I can't say the sensor is faulty, I'd have to check the circuits.
I did see a bulletin about acceleration sag and tranny shift, but, that was for a warmed-up engine, I don't think it applies here?
