2002 Chevy Impala 6 cyl Front Wheel Drive Automatic 100800 miles
A month ago my I had my catalytic converter replaced because it was cloged. And after it was replaced the check engine light came on and stays on. I was told that the O2 sensor was bad so I replaced it but the light still came on.
How many O2 sensors are there 2 or 1?
Do you know what the problem is?
