E90 M3 Misfire and Random Codes. Help!

So, lately I've been noticing hesitation at low rpms and it has now started to throw CEL's.

I'm getting misfire codes on cylinders 5,6,7 and 8. Along with a random o2 sensor codes.

P2298
P112D

The car has become un-drivable at this point and keeps going into limp mode.

57,007mi on the odo...all stock.

Please help! Thanks

So safe guess it's probably an o2?

Yep.

Please excuse my ignorance, so should I replace the front O2 sensor is there more than one?

Bank 2 is drivers side. These errors are for the pre-cat.

Yes, there are 2 O2 sensors per bank. Pre and post cat (main cat, nothing is monitored on the secondary cats)
