Don't be hating! Your ass is always calling for my professional JDM advice BUT ANYWAYS. I recommend doing it on cylinder #1 to begin with if you don't know which one it is just trace back from where it says 1 on your distributor cap most likely the 1st plug on your left (pass anger side).

BTW I also own a 2000 Nissan Altima. Still needs a few things but I'm working on it too.
