When youāre speaking of the random misfire, are you getting the P0300? If so, had you checked the crank sensor,h are SS or connector as mentioned above in post # 11? Iām only mentioning this again because it has been found the crank sensor can cause many sporadic issues, even if youāre not getting a direct crank sensor DTC.Getting nowhere fast with this issue. Checked plugs again, all look the same. Random misfire continues to pop up. I re loaded the tune, did another relearn on the crank.. Still getting the CEL on some runs.
What heat range are the stock plugs from a 2021? Could I throw them back in with a gap of 28 to see if the issue goes away?
I figured out how to data log with the Livernois tuner but have no idea what I'm looking at and can't seem to get the files to save anywhere useable.

I'll have to bench test them tonight. I've only been visually checking them. I am getting the po300 code only, no specific cylinders.When youāre speaking of the random misfire, are you getting the P0300?

Have you checked each spark plug using a multimeter to see if they are good? A spark plug can physically look fine, but may have internal damage. Just Google āhow to check spark plug resistanceā and thereās quite a few vids to demo how to bench test the plugs.
VCT solenoids could cause misfires too, which is what the recent fix was for this M6G member:

The tip is scraped because it may have come in contact with the tone ring. The crank sensor reads the tone ring - if that ring gets bent (hope it didn't), you're going to end up with misfire codes., or worse case, car won't start.Well I cracked the freaking sensor when I put it back in, nobody local has one from what I can tell..... Advanced auto has two that show up but look nothing like it should.
I'm guessing like most other cars, OEM is best anyway for these types of sensors?
I could see the crack where the bolt was after starting the car and hearing something touching. The tip was also scraped up.... Would the scraping be just from overtightening or something else. I also noticed the red o ring is missing....
