O2 Slow Response

O2 Slow Response
Current setup on the car was completed in May. At that time, I installed a pair of new 13111s into the headers I just installed. Tuned the car and all was well. For the last 2 months, the car has basically been parked, although I did frequently move it in and out of the garage. Pulled it out to start driving it again last week and it sets the O2 slow response code for BOTH banks. The sensors have less than 500 miles on them. I cleared them and they came back on 50 miles later.
Did I damage the O2s by starting the car, backing it out of the garage, and turning it off? If thats not it, what would cause both sensors to throw the code at the same time like this?
Thanks

Did you get on it any? When my pcm resets from unplugging the battery that code stays in the not ran section on my predator and will set the ses if I dont do a wot pass.....I have the bosch sensors also and once I do a few good runs the code goes away and hasn't come back up

I had the same problem and couldn't figure it out, so I bought new GM sensors and ran a test. I installed one GM and one Bosch sensor, then datalogged the two during normal driving. Sure enough the Bosch sensor was switching noticeably slower compared to the GM sensor. The LTFT's on the Bosch side were also way off.

I did the exact same thing and had the opposite result; no ****.
