I put in a bottle of Lucas fuel injector cleaner. Wondering if my injectors may just be clogged from gas that was sitting for 8 months??
I'm going to take them out today and test them to see if they're all working.
Anyone have any other suggestions?

Thanks Vegetta
So I switched injectors 1 and 3 and 2 and 4.

Then I took a look at the FPR:

I guess I'd probably call that debris/rust?

I then cleared my codes and went for a ride. Logged 14,15,16. Cylinders 3 and 4 were still misfiring the most, but now cylinder 1 misfired some and cylinder 2 misfired maybe 5 times.

Scan only comes up with DTC's for cylinders 3 and 4 though....
I'm confused. Can it still be a problem with my FPR even though the misfiring is staying in cylinders 3 and 4? I feel like if debris in the fuel was the problem, that it would just clog the injectors and then the misfire would follow the clogged injector from cylinder to cylinder.

Think maybe it's a corroded wire somewhere?
Would you still advice replacing the filter and fpr?

oil was replaced 2 weeks ago, I'm planning on changing that after 500 miles.  
I just replaced the plugs yesterday with brand new bosch ones when I replaced the ICM.
I'll replace the fuel filter and fpr... Is this a good time to upgrade fpr? or do I need software change in order to run a higher fpr?

I looked for vacuum leaks, but couldn't find any. I don't have a way of actually pressure testing the system, but I'm thinking about just bringing her to a local shop that's been helpful to me if I can't figure this out in the next week or so.
I have a boost gauge, i spool 5psi at full throttle.

Also, my ground on my valve cover for the coil packs looks like ****, I think I might cut it and run a new end... There's only supposed to be one ground for the coils, correct?
