I'll continue to wish you good luck...…. I think you are going to need it.
If the rough idle is still present, something is still wrong with the car. Start thinking about a warranty claim if this new dealership can't figure it out quickly. I bet you are going to have issues with the injectors again in the near future.

Was yours missing all the time? ‘21 SS 1LE here only misfiring P0300 on track.. once at the end of a straight around 120mph and once part throttle at 40mph or so. If i disconnect and reconnect the battery the P0300 goes away and the rough idle and misfires stop, until you go back on the track.
I disconnected the battery again and was able to drive all the way home 2hrs 85mph no issues. Got home did 5 hard pulls, no issues... what the hell could that be? I’d think if it was something mechanical it wouldn’t go away by resetting the battery.. i bought this car for track days its really frustrating it will only do it on track, dealer wont do anything bc the CEL is gone, which i get, but they said they did a “software update” to fix it? Any of you guys who have dealt with this and had different issues, what does this sound like to you? |

I have been researching ZL1 for 6 months.
I kept reading about issues with 2017-2019 engine problems oil pump etc etc. Doesn’t GM know about this pattern? It’s all over the forums. Hopefully it’s a quick fix |

OP has a different problem. Could just be a fluke. 2019 models the oil pump was changed which is why you don’t see anyone reporting this. A lot of other misfiring/similar issues were simple fixes. Plug, wire etc.

Mine seems to have been a simple fix as well.. plug wire number 1 made a slight click when I pushed on it, no issues at the last track day, hoping that was it

Update: Spark plugs were replaced and the dealership wants to give me the vehicle back.
In six months and less than 500 miles, the spark plugs have been replaced three times. There is a clearly an underlying issue that the dealership is failing to address. Any ideas? |

Where in Orlando are you taking it to? If you don't want to post it here just PM me. I'm in Clermont and trust the dealer here.
