Default Multiple engine misfire???

Alright, car is missing when driving. It seems like it is a periodic misfire, meaning one or two cylinders are missing, not different cylinders everytime. I changed the plugs/wires and nothing happened. I plan on checking the coils tonight, which I have no idea how to do.
Does anyone have any other ideas of what it could be, and also how to check the coils?
I am throwing the code for multiple engine misfires and also a 02 sensor has low voltage. Would the 02 sensor have anything to do with the misfire?

What are the codes? Car is trying to tell you what's going on. Is the 02 sensor with low voltage a precat sensor?
