I had the check engine light checked out and it showed I had a bad oxygen sensor. I changed out the oxygen sensor twice and it still keeps coming on and has the same code. The car doesn't idle smoothly, the rpm moves a little up and down. In the morning when I start the car I can smell gas. The Hyundai is a 2001, 4 cylinder, automatic. Mileage- 109, 000. Thanks I changed both oxygen sensors.

Time to stop trying to be cheap and have it repaired by a professional mechanic.

There are more than one O2 sensors. Did you make sure you changed the correct one?

I agree with the above-I changed the wrong one the 1st time. The 2nd time, I was fine.

A scan tool will only tell you what part is tripping the code. Just because it ways o2 sensor doesn't mean they are bad. You could have an exhaust leak or an intake leak. This will cause the air fuel mixture read by the sensors to be out of spec and therefore trip a code. I would recommend getting it looked at more closely.
