I was driving home today and these codes popped up. I set my aeroforce to scan misfires and sure enough when under throttle I was having misfires in what looked like all the cylinders, the kicker though is that the car runs perfect and has absolutely no loss in power from what I can tell. I'm not even seeing any knock or anything. I did just do a case relearn using the aeroforce yesterday and noticed the procedure was different then any other case learn I've done using a tech 2 or dhp

Ya I'm just not sure if the misfires im seeing are real. You would think if it was bad enough to throw a cel it would be noticeable.

Don't be so sure. I once swapped my Regals trans and found the issue to be worse and consistent. Ended up being a bad coil. Life is good when you have a spare trans lying around and you don't mind swapping. Literally got to the point of shotgunning parts because it had to be electrical and I couldn't see it on a scanner or feel it driving.
