its a g8 with moderately size cam. seems to do it more at higher loads, at some point it sounds like i'm hitting a two step.... its got new plugs, wires, and checked the plugs a few time. checked the fuel pressure at idle, pulled the valve covers and it seems fine, nothing loose. pretty much done everything but compression test and replacing coils.

i've disabled long terms to see if that was doing it, and also disabled closed loop all together. ignore the afr ratio on the log, its shows lean due to an exhaust leak by it. when i tuned the car i had the wideband in the factory o2 sensor location and it read fine.

You can log individual cylinder misfires but if you turned off misfire detection because of cam lope temporarily re enable it.

i did reenable it, but its not really consistent. in this log it shows alot for 1 2 and 6. other times it shows 0.
