Just replaced/cleared codes for the primary and secondary oxygen sensors (bought and installed both new). CEL was off for a week. Now it comes on for a day then turns off, by itself, for a day etc. etc. Have not been able to get to a code reader to check the code being that the light comes on when it wants. Anyone have any experience with this happening when replacing the o2 sensors?
