Data logs at WOT are rock solid and spot on. Even at 50% throttle everything looks great.
Cold Idles are rock solid as well.
Once engine warms up to full operating temps is when the misfires begin. Misfires are worse in hot weather and slightly better in cooler (less than 80 degrees) weather but still present.
AFR Bank 1 is 110% to 118% when misfires are present and sometimes pegged at 120%+ . while AFR Bank 2 is usually within 5% of 100.
"Multiple/Random cylinder misfires" and "Cyl 5 Misfire" codes sometimes accompany these misfires.
The moment I rev my engine above 2000 or so rpm misfires dissapear. And the moment I start driving and apply anything more than 10% throttle misfires disappear as well.
I can provide datalogs as I have many for idle misfiring.
