A few years ago, I accidently put too much oil in my car and she apparently threw it up all over under the hood. Ever since then my engine light has been on and diagnostics say its my O2 sensors. I've had them replaced 3 times in 6 years (right before inspection) and the light always comes back on a day or two later. Could there be some oil residue left where the sensors go that could be affecting them?
