I am not sure if the misfire counter includes pre ignition, failed ignition, or both.

The plugs and coils were replaced about 800 miles ago, (the audio clip was with the new coils and plugs). One thing i cannot verify was the fuel at the time of the audio clip, since i had just gotten the car back from the dealer i dont know if they filled it up and with what or if the gas had been sitting for a while in the car.
