how long would it take to fix an o2 sensor in a 1997 chevy cavalier?

You can do it yourself, probably but why are you changing the sensor.
If you got a trouble code that points to the sensor, that doesn't necessarily mean the sensor is bad.
Most time it means you car needs a tune-up very badly, new spark plugs, spark plug wires, air filter.
This is because the ECM gets the reading from the sensor and the sensor is saying your exhaust stinks and the reading it's getting is not what it's supposed to get.
The reading from the sensor could be correct and the sensor might be working correctly.

== it takes a computer check on the engine to figure the right sensor to replace ... if you know which one to remove and replace then it should not take more than 30 minutes ... the trick is finding the right one to R&R>>>> the local auto supply might be able to tell you which part is most likely to be out and if you ask where is that thing located under the hood --- the counter dude will show you.. Those guys are helpful and you can make a friend (( you will need more auto advice and parts )).....
