    Do these look like misifres?

    Replaced what I think was a faulty coil pack that would make spark but still somehow cause a misfire that was hard to catch as it barely showed up. Almost thought I was going crazy moving the coil around and barely catching it misfiring from time to time. I thought these things were go or no go type of deal not partially faulty as this coil seems. Couple short clips of logged misfires, just hoping someone can verify that they actually look like misfires. I would love to mail this coil off and have it checked by someone more experienced. If this unit is partially faulty it possibly could have been a problem for the last few years. Truck does seem to idle a bit better has me wondering if I should order a new set of coils.

    Looks like you have some strangeness on bank 1 that's not present on bank 2. That's looking at your "coil moved" data log.
