Check engine light came on and stayed on for about last 10 miles while out running errands. Conducted KOEO and KOER tests(car was still warm). Codes 172 and 176 were read during KOEO test. Code chart states this is "Lack of Oxygen Sensor (HEGO) switches, indicates lean (RIGHT SIDE)
Code 176 is same except for LEFT SIDE.
After both KOEO and KOER tests were conducted, I started engine again and let idle for a few minutes and CHECK ENG light did not come on again.
I've never changed any O2 sensors on this car. Think this is culprit or something else? First time I've ever had this code.
Car is stock
I did a search on this question and found very little.
