    Either bad plugs/wires, or possibly the ICM. Seems kinda odd that it was only the rear cylinders.

    No I think he was saying his motor was ran by cats on wheels and he let one go but it didn't make a difference

    Sounds like a bad coil pack. Pull each plug off and check for spark going from the wire to the coil pack for those cylinders. I use a screwdriver to do this but be careful you can get a nice shock

    You should find that, those rear banks are useless once they go missing...
