Change the O2 sensors as a precaution. Its always a good idea. You can do it yourself easily/cheaply and the mileage usually always improves. I had already changed mine last year so they were fine.
They won't cause a SES light until they are completely inoperative even though they are feeding the computer inaccurate readings.
