I'd try cleaning the intake with carb cleaner. You'd be surprised how nasty those get. Fresh hi test and a can of good fuel system cleaner as well. There may be some carbon ect on the O2 sensors causing a slow read. I've heard of taking sensors out and cleaning them with electrical connection ?? cleaner. Could be they're just sooted up. Some one else here may have a better idea though. Hope this helps.
