How to tell which cylinder is misfiring without codes

I'm getting a solid miss, but it's throwing no code. Short of cracking the whole thing open and looking, can someone tell me if there's another way to see which cylinder is missing?

Start unplugging injectors, maybe Cheezit can give you a better idea.

LMAO. I suck at the search function... I only knew about it because I started it. there was a lot of issue with people loosing the clips and I could figure out how they were doing it.
