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.
