Misfire Channels
Could someone tell me what channels need to be logged while scanning for misfire on 2002 ls1? I have a miss that I can feel and hear at light throttle but I get no dtc's. Not knowing what to scan, I pulled all the misfire channels and got no hits. What am I doing wrong?

So after some more research it appears that in order for misfire detection to work you can not have any other dtc's present as I did because I was running in sd with maf failed. I then renabled the maf and now I can see the misfires. Now my next question is how many misfires are acceptable? I have around 100 or so on cyl 2 and around and about the same on cyl 6 while the rest are 20 ish.
