    One coil does 1 and 4, the other 2 and 3, sometimes the lead length gives a clue.

    Doesn't matter,both leads fire simultaneously . Also,the coils fire twice per crank cycle (wasted spark). But only one spark has fuel to ignite, hence the term.
    You have a 50/50 % chance of getting it right,or wrong. It's pretty simple
    1 & 4, 2 & 3.
    Like Wizard wrote,check the lead length. I can't imagine that all four leads are the same. On coil has shorter leads than the other.

    1 and 4 are interchangeable as are 2 and 3.

    I was a little slow on the draw that time lol

    No you can not "just remove it" the engine has to be in the correct position or you risk messing up the cam chain timing. There is a detailed procedure in the service manual, I suggest you get one if you do not have one already.

    Please explain why you think it needs to be removed because it is sticking.

    Valve adjustment is critical , have you checked them?
