I need some help please. I am doing my first LS swap for a friend and ran into an issue. He bought a really nice harness complete and ready to go. The issue is that the o2 sensors are not working properly and it is not going into closed loop. We tested the o2 sensors and they seem to be working (getting warm when powered). Let me know if you see anything out of the ordinary or any recommendations.
Thank you,
Luke
