1 O2 Sensor problem of the 1998 Mazda 626

Failure Date: 01/01/2004

I have spent over $2000 trying to get my engine light to turn off. Nothing works. Now I am being fined for not passing inspection. What is going on? I have been having this problem for 2 years. After various repairs the light would finally go off. Now it will not and has been on for over 6 months. I have had O2 sensor and cat sensor replaced, since that is supposedly what the code was. Still nothing and noone seems to care.
