Chasing a P0304

So I’m about to begin chasing down a P0304 misfire code with a noticeable engine knock on a ‘01 with 298+ on it.
Brief history:
Family passed down since purchase, this was a dealer base model used initially for test drives/dealer service loaner for the first 1000 miles or so. No frills classic white but great to drive.
Outside of regular maintenance:
Traction battery full replacement ~2012
Wheel bearings replacements all around- front 2019 back early 2020.
A laundry list of smaller repairs and standard maintenance between then and now...
Car grew up in IL/KY before moving to the harsher NE and driving NY/VT/NH/ME the last few years and visiting everything East of CO lol.

Spark plugs I just changed our and it’s running a bit smoother all around naturally. Equal wear and nothing stood out.
At idle it’ll run smooth but driving it’ll start misfiring at about ~35mph.
I plan to replace the original coil packs next but thinking it’s probably a fuel injector based on what going on.

A: Would anyone happen to have the firing sequence of the cylinders
B: Thoughts recommendations before I eventually drop it off at the shop, as I don’t have the equipment/space to tackle that job currently.

Ideally want to take care of the misfire and get it back to my daily driver so I can hit the 300 mark.

Thanks in advance
