Yeah? Cars a 21 SS 1LE cold air intake corsa axle back, 5900 miles, was a Michigan car now a Florida car. I tracked my 2020 1ss all the time no issues, you think it needs cooler plugs?

Well if it does it on the racetrack and logs CELs, then they should remain in the car's computer, should they not?

So when it happens and goes P0300 on the race track, the car has an undriveable misfire. If I reset the battery it goes away, there’s no dealers near the track and it’s far away so I reset the battery again to drive home and the dealer says there’s no codes because of that. It seems like I really need it to break and have it flat bedded for them to take a serious look at it.
