Sounds exactly like my problem. I'll keep you posted if I figure anything about. I'm also going to be cleaning the fuel injectors when I replace the front o2 sensor. Good to hear I'm not the only one having this problem since it seems really weird to me how consistant it is and only at spot in the powerband.
