Seems like the header O2 is unplugged, or has a broken wire.

It is also possible to plug the rear and front O2 sensors TOGETHER.
Make sure that is not the case.

Soopsaaa

My car is reading these 2 codes as well and sputters bad at 6k rpm wot unless I ease on it then it goes to 9k, what do I do??

Soopsaaa

I also just put a new upstream O2 sensor on and it and that's what it reads this now.
