The coil packs are ridiculously easy to swap. I'm in 92618 with code scanner if you need help.

Thanks, I appreciate that. I am 98% sure it's the coil.

Scanner said p304. I swapped coil 4 with coil 1 and re-scanned. It gave me p301 and p300. Also said p304 which I assume was just stored, yeah?

And p300 is just the random misfire code right?

So it sounds like just need a new coil pack for 4 unless anyone disagrees?

Also, don't know if this means anything, but 4,3, and two packs were clean and dry. But number 1 had oil on it. Is that normal or a warning sign?

Your codes are right. You should reset the codes between tests so you don't get the stored ones coming up again. If it still comes up, you may have a different problem. More to that point, substantial oil on the coil pack isn't normal. You should pull the spark plug and take a look at it. Get a flash light and look down inside as well.
