Air leaks can cause a missfire too,Early GM 5.3s are this way.A blown out intake gasket will cause a missfire on a GM 5.3.Wrong brand spark plugs used too and I see this a lot with Bosch plugs.
Thanks for the very informative video, but a question on the detection the o2 sensor makes,does it detect the excess amount of fuel or just the amount or lack of oxygen in the mixture? i am not sure if you guys left the note below or someone else did, just want to clarify thanks..
my check engen light was flashing because i pulled a plug wire i hooked it back up the light went off and i am happy

NOTE: at 01:06 The O2 sensor or oxygen sensor does NOT detect excess amount of unburned FUEL. The O2 sensor detects the amount of OXYGEN.
