Ok so my CEL comes on and off, sometimes and sometimes the car stinks (like a fart or rotten egg smell, embarrasing when ladies ride with me).
Took it to autozone and that code came out. Now, the thing is, they told me that usually the problem was the O2 sensor. Now that doesn't make any sense. If it was and O2 sensor issue the CEL would trow me a code for O2 sensor, and i suppose that there's no type of sensor inside the Cat.
What could it be? O2 sensor or actual Cat is malfuncioning?
