Error Codes on 01C320

Hello all! Just joined as I just purchase a 2001 C320 this week!

Having some unusual issues with my 'new to me' 01 C320 yesterday. Started the car and it was idling and driving very rough, to the point of shaking everything (including me) in the car. Check engine light came on, and for a few seconds flashed then remained constantly lit.

Went to Autozone today and had them scan the codes for me, came up with 6.
P0300 - random cylinder misfire
P0301 - Cylinder 1 misfire
P0302 - Cylinder 2 misfire
P0305 - Cylinder 5 misfire
P0170 - Bank 1 sensor 1 control adap. at cruise
P0173 - Bank 2 sensor 1 control adap. at cruise

From what I have read it could be a few things ranging from O2 sensors to a mass air flow sensor, to a vaccuum leak. Any idea on where I should start or what the cause is likely to be?

Thanks for all the help!
