I have a misfire in my 2006 6.0. P0282 #8 low circuit. #8 also fails buzz test. I did a power balance test in AE and could see at #8 engine dropped off. Seemed as if #1 dropped as well. And then picks up through the remaining cylinders.
There is a monitor in AE "misfire percent delta". All read 0.0 except #1 and #8. #1 reads 64.20, #8 reads 251. 42. What is this and what is it telling me?
