What does the computer actually have to see to set off the misfire code? In other words how does it know that its misfiring?

ill see if I can dig up the page in the service manual

So it is now narrowed to what seems to be cylinder 6 as it has now thrown the code at idle for that particular one. If that number 6 is misfiring when getting on the throttle sporadically would it cause p0300?

Additionally it seems that at idle (started it up and let it sit there) the cats are getting up to about 1,250 degrees F if that makes a difference
