The best advise i can give you is take it to a Technician . A good shop that knows how to read sensor graphs. I use to use a Snap On "BRICK" (scanner) Gives you multiple inputs on all sensor. And If you knwo what a sensor should be doing(or looking like) you will find the problem.

liek i said dont replace the sensors unless your sure it is the problem. In this case i think you would have benefit from taking to a shop .

since sensors are a arm and a leg $$$.

im pretty sure hten u might have a engine problem, fuel system problem. liek i said b 4 ruinning to rich will damage your o2 and cat . the saem goes for runnig lean.
