This is why you can erase some codes and they take some time to reappear.
If you were having an issue that was immediately harmful to the catalytic converter the OBDII system would trigger your check engine light on the first event.
A misfire is an example of such an issue.

Thanks. It looks like the problem is much more easy now. The leak is not very obvious but actually intriguing the fault codes. Do you know how much it takes for a independent shop to fix it?
