Got another check engine light..........
did a scan on it and got a all clear the first two times...then on the third test pulled a
173 which is Lack of Oxygen Sensor (HEGO) switches, indicates rich (RIGHT SIDE)

Now to my question....is this maybe a bad o2 sensor or my maf sensor is goin down????


i pulled theses codes with the car off........is there any other scan i can do?
 
Ok

The car is running way too rich, code actually reads adaptive limit reached, still rich bank 1.


Usually, it's a bad O2 sensor.

Otherwise, you're dumping too much fuel...Any recent changes to the car??
