8.1L #7 misfiring
Hello everyone, I'm getting my ars handed to me and now I'm reaching out to you all for ideas, here's where I am at; new plugs, new wires, new coil, new cam sensor, new crank sensor, complete set of "different" injectors, swapped ECU. Performed a decarboning process (water and oil mixture) compression test, 150# on #5 & #7 didnot test compression any further.
I am now searching for the needle in the haystack.
How does the ECU determine a misfire?? Does it read the knock sensor and the firing sequence? If so it could be a flywheel bolt hitting,? ( I did not install the transmission, so I cant garantee anything). Could it be a restriction in the intake? Something on the top of the piston?
These 8100 are not cheap to work on so I really don't want to go all shotgun on it, I've invested a lot already.
Has anyone ever seen this before??
