First of all, just because it list an o2 issue, doesn't mean the o2 is at fault. Part stores love the people that buy parts and do not care if it fixes the problem, they will sell you the part though. Do your self a favor and find out what is really the issue. Don't you read all these post who say "I Have Replaced The O2 Sensors __ times and the light is still on saying the O2 sensor".
