1999 Saab 9-3 are O2 sensors required
I have a 9-3 which was recently stolen. I got it back but they took out the catalytic converter. Im looking at generic replacements. So my first question is: whats the cheapest best option to replace the cat?
Next up from the looks of things they just yanked the catalytic converter out so i have no idea if the O2 sensors are going to work at all. How vital are they to the opertaion of the vehicle? Can i survive 8 months till its due for smog certs without O2 sensors.
