I'm also thinking it could be the spider injector but not sure I've heard its a common problem with these trucks

The injector assembly does have its issues, but it usually will set a cylinder specific DTC. With P0300, I'd bet on secondary ignition.

I'm leaning more towards plugs and/or wires cause it ran perfectly fine before I did the work and it sat a for almost two months due to some out of town work.. would that make sense?
