what did they do before 02 sensors....go to any cruz night, stand at the exit and watch them all leave.
After 10 cars your eyes and sinuses will be stinging from all the unburnt fumes.

No they didn’t and don’t.

I can find the same thing on **** with O2 sensors.

An O2 sensor won’t make you a tuner. All it CAN do is shorten tuning time.
