Got the CEL this morning but it runs fine. Any ideas? Obviously no AFM in the M6. But curious if the NPP motors are handed and maybe I got them mixed up.

Welcome, as others have stated check for exhaust leaks first. While underneath the vehicle swap the O2's from left to right (lot's of rust penetrant before attempting removal and add anti-seize to threads before re-installation). During removal pay close attention for damage to the wiring or harness on the sensor in question. Clear the codes and if the code jumps to the opposite bank you have your culprit. If the code doesn't jump sides I would recommend calling the manufacturer directly for additional assistance.
