Are there cylinders that seem to misfire more than the others? I get that all 8 are showing counts, but, lets say you graphed it... would there be 4 cylinders that tend to have more misfires than the rest? Can you post a screenshot of the cylinders with a bunch of misfire counts already? I'm curious as to which cylinders they are and where they are in the firing order and where they are on the engine.
I re-read your posts. So, the ignition module has been replaced already? You have or have not replaced the fuel injectors in it? Does the plug for that specific cylinder that continuously misfires look different? Have you done the "dollar bill" test at the exhaust to check for a bad valve/head gasket?
