DO I NEED TO REPLACE O2 SENSOR? OR MY CATALYTIC CONVERTER? OR WHAT? PLEASE PLEASE HELP ME!
O2 sensors are good for 80 to 100k miles. a simple test for an O2 sensor is to remove it and shake it. If it makes any type of rattle noise then replace it. Also while the )2 sensor is out you can run a back pressure test.
