Misfire in cylinder 2/CEL

This started 2 winters ago. When it was cold and the truck was idling the truck would shutter a little bit. I by accident put in premium and it seemed to have gone away. So I tested it over a couple fill ups. It would go away with premium, and come back with regular. No CEL.

When the summer came and she ran perfectly. I ran regular gas. No problems.

This winter had some problems with it shuttering, nothing too bad, ran regular gas for the most part. Still no CEL.

Now its getting warmer and shes starting to get bad. I can feel it while cruising, it stumbles and then recovers and repeats for a minute of so and then stops. Doesnt have any problems while accelerating. The CEL came on a couple days ago. I pulled the codes P0302, P0000, and P0000 (thats not a typo). P0302 is a misfire in cylinder 2 and from what I have found is P0000 is a read error on the scanners behalf. I cleared the codes and the same thing came back as soon as I started it up again.

I pulled the plug and it looked fine. I threw an ohm meter on the plug wire and it came back very low, which is good.

Where do I go from here?

check your injector. noid lights will help if you own a set. questions
How new are your plugs?
How new are your wires?
Also i could be some of the following
Incorrect fuel pressure. Unlikely
Ignition Related sensor.
Faulty Injector

Plugs have 40k on them and wires are stock. both seem to be fine.
