Multiple Cylinder Misfire P0300

Genosphere

The code from my OBD, yes. An no I actually read through multiple forums, videos, discuss with people etc. to try to narrow things down. As for dropping the oil/filter, I'll probably need to do it anyway if I have to get into the timing cover and it turns out to be leaking from what ever seal; I also would be doing a post winter oil change soon if this didnt happen so the filter was coming off one way or the other.

Side note, I am going to take a look into the IVT solenoid/sensor before i rip apart more. Seem like a possible culprit and it may keep me from having to tear down the front end for now. Doing a little more digging before i start wrenching today or tomorrow.

I appreciate the input on the oil filter, but please do not assume i just type "x" things into a search engine and read the heading thinking, "thats it!" I prefer to do research and cross reference especially on potentially serious matters.

Just a few sources for some generic info:
ENGINE Rebuild, P0011, P0021 Help!
