Keeps having o2 sensors go bad

I am sure its a coincidence but I was scanning the car with freescan and I reset the BLMs and now I get a lean code when idling. Went and drove it and still comes back. Weird. I have to say this car seems to go through O2 senors frequently. maybe I am using bad o2 sensors, maybe I have a tune problem...its been a great tune from MADz28 for years...seems to run well.

NTK, Standard are 2 of the brands I think I have used on the car.

Most people choose to stick with AC Delco AFS75 replacements.
