Random/Multiple Cylinder Misfire after Timing job?

Random/Multiple Cylinder Misfire after Timing job?
So my timing is dead on, and after getting everything back together i overfilled the oil by accident, which in my haste it flooded the cylinders. Emptied the excess out, and have been trying to start it again and imI able to get it to run but with the following problems:
I'm getting cylinder misfires on cylinders 5,6,7,8, and 4.
I'm also getting a p0300 error code, which reads "manufacturer controlled fuel and air metering".
The car will not run unless i keep giving it gas.
So what should I do?
The manual is of almost no help here because it gives very little information as to what p0300 even means, all it says is check injectors, and ignition coils.
After starting it again and it feeling better, I tried opening it up to expel oil in the cylinders. With it floored I was only hitting 4000 rpm, and now after that there is some oil smoke coming from the exhaust manifold in the engine bay and a dripping sound.

I am not sure how overfilled oil gets into the cylinders unless you filled it to the point where the crank slung it around and it got sucked into the PCV system. If so pull and clean the spark plugs and try again. Of course once the oil level is correct.

I've drained the oil to correct levels. And cleaned the spark plugs, and it's still running awfully. I suppose I could open it up again and check my timing again. Other than that i don't know what I can do, unless it's the camshaft position sensors.

You could try spraying a little starting fluid into a vacuum line to see if it smooths out with more fuel, that might point to a dirty MAF sensor or a big vacuum leak. If that doesn't change anything, see if you can run it a bit and then check for any spark plugs which are colder, i.e. specific deal cylinders vs poor running on all 8.
