2002 A4 3.0 cam and misfire error codes

OK so I have some error codes I can;'t seem to figure out where to start looking for the problem. So here I am. My error codes are as follows.

End of report.

Any help would be great.
Thanks

Did you replace the timing belt recently? Based on the codes, I would check the timing on that bank first to potentially clear the misfire and P0011 codes. Look at the wiring for the O2 sensors for the P0160 code.

I didn't do the timing belt YET I'm thinking this might be the problem but I also think it might be the cam sensors. I just don't know where to start with it.

OK so I'm going to replace some sensors. What I'm wondering is if all 4 sensors are the same or if they have different part numbers? What is the "A" side? Driver or passenger side? I have a bank 1 and 2 for the "A" side.
