    You probably have a blown head gasket. The codes you have are for misfires.

    Thanks. That is what I though but I pulled two plugs from the side that I see some leaking, but they looked fine.
    I guest I should pull all the plugs and see what they look like.
    Regarding the misfires codes, should all the coils or just one?

    Thanks again for your help
