Running Lean/Rich

Running Lean/Rich
I'm having a problem with the P1131 and P1132 (Running lean first, now its rich). I can't find anything physically wrong. There is no black smoke and it runs great (no mis-fires). It keeps going from lean to rich to lean again, etc... It's a 98 cobra. I don't know what else to do. Anybody have ideas?
