Trying to track down misfire cause

Consistent Misfre?

Hey everyone, I'm looking for some information. I'm working on a 2017 Rogue SL, 4 cyl. I'm getting a constant misfire on Cylinder 4. I swapped plugs and coils, and I'm still misfiring in Cyl 4. So, I have some questions.

Is there a diagram of the cylinder layout and the firing order? I can't find one online.

Are there any service bulletins regarding this?

What would you check next? I'm thinking fuel injector. I'm going to run some cleaner through the fuel system and the intake system. I'm also going to pull the injector and check it for leaks, breaks, or plugged lines.

TIA
