Haven't experienced the sleepy O2 sensor symptom but have heard that replacement can clear the problem. Any changes in gas mileage?

When I had CEL, I replaced the gas cap seal with a Viton part and insured the filler neck surface was clean and free of any blemishes. Solved the problem and CEL is off.

Let us know if O2 sensor replacement solves the issue.
