I have a 2003 Alero with 45000 miles on it. The "Service Engine Soon" light
has been on for quite some time now. A friend told me that I could have a
bad O2 Sensor. Can anyone tell me where on the engine this sensor is
located? Thanks!!
There at least 3 sensors on that car, which one, plus it should be properly
scanned and the problem diagnosed, not just put in a part it may not need.
