A scan showed an O2 sensor code. These lights having been coming on and off for about 2 weeks. The car slows down when the reduce engine power light comes on. Is this likely to be a serious repair cost? The car has been well -maintained and oil changes have been on time. All gauges work while this is happening , just the car slows down. What could be causing this on such a fairly new car?
