O2 Sensor on a Carb Engine Question

My experience with it was when Holley sent me a bad ignition module.
I had random constant bad misses and my afr was showing lean as hell.

It wasn’t lean, but just reading unburned 02.

You wouldn't believe how many calls my tech dept gets that start with "yeah, it ran amazing before it went to the body shop" unbenounced to them....the shop started it and moved it 10 feet at a time, about 30 times, over the course of having it lol
