So after a scan the codes are:
PO130; PO134 O2 sensors
PO456 Gas Cap
PO105 MAP error
PO138 O2 Sensor

Looks like O2 sensors and the MAP sensor. How difficult are these to change out on a 2002 C32?
Any recommendations?

The O2 sensors will be hardest they will be rusted on u need special socket makes lot easy

Could the MAP Error cause the O2 sensors to show a fault? Should I replace the MAP first?
Car still seems to run OK.

I would do gas cap and map first then reset codes drive for a bit see if O2 code comes back
