I would think if mine was either of those issues you described it wouldn’t go back to normal and make it all the way home at 85mph by reconnecting the battery?

Mine would come and go at a specific RPM spot above 5k rpm. It was the harness. One of the contacts locks broke and it would back out during insertion.

Join the club.. Same thing happened to me. I am on my second visit since they replaced the same fuel injectors, spark plugs, and coils.

Just got my spark plugs replaced for the third time.

Did all this happen with a stock ZL1? I assume yes because it sounds like you had this done under warranty.

Something is very wrong with fuel, fuel system or tune if you had to replace plugs 3x on a stock ZL1 running premium or high octane unleaded race fuel only, with no additives like octane booster.

Yes, my car is stock and I run premium. I previously had an M2 so premium fuel is not new. Sorry, not trying to hijack the OP's thread. They just have a similar issue to me.

I assumed it was premium, but maybe with additives or tune with E85.
