    So tell me why is your firing order confusing? why is there an 8 on your firing order when there is 6 spark plugs.

    1. Hey Arminda, Thanks for pointing this out. Just to clarify for everyone, the 8 on the diagram is supposed to be a 6 as stated in the other parts of the article. I must have missed my morning coffee lol.
