All cylinders misfire detected and random fault code

[mbplace]

Alright so I got an SES light that popped up the other day and I am thrown off a bit by what the codes are telling me.

The codes:
P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 -- all cylinders misfiring

-and-

P3AA8 -- cannot find it anywhere.

My question is: this has to be a malfunctioning O2 sensor or something for every cylinder to be misfiring at the same time, right? Not experiencing any loss of power and engine sounds perfect. And what is that final fault code?? I cannot seem to find it anywhere.

I would really appreciate any help!
