Need some 6.4 guru advice...

(2008 F350 KR) I was driving to work this morning and I started feeling some vibration like I had a flat. I pulled over to check and noticed a puff of smoke from the tail pipe. Tires looked fine so I got back in the car and noticed a definite misfire.

When I left this morning I thought the truck sounded just a tad rough but it drove fine while I dropped off the kids. I then filled up with gas (could be bad gas?) and set out on my 42 mile trip to work. About 8 miles into it is when the truck started shaking.

I do not have any check any lights and there was no overheating but there is definitely some kind of misfire going on.

I just put a scanner on it and I'm getting a P0302, Cylinder 2 misfire.

Am I screwed? What should I check/replace first?

Could be an electrical connection issue with injector 2 or more likely (in my opinion) a failing injector. Hence the white smoke.

Do you have any mods on the truck? Is it deleted? How many miles are on the truck? all this info will help for sure. Also, how old are the fuel filters? That would be the first place I would look into. Also, don;t drive it any more than absolutely needed at this point. Failing injector could lead to melted piston.

Filters and oil replaced 5K ago, I'm due for an oil change and was going to do one this week, along with the filters. Truck has 127K on it and has 5" exhaust with H&S tuner.
