Delete R is an even worse solution..it clears the code every 5 minutes, including any codes that aren't post 02 related.
I have never heard of a 02 sensor extension for the rear 02s cause a car to go into limp mode. The rear 02s are just for monitoring the cats and are not gross adjusters. You had another post I believe where you stated this and you didn't leave any more details.
