O2 sensors replace in pairs?
I thought I remembered reading that the O2 sensors should be replaced in pairs. I can't remember if the pairs should be both the pre-cat or post-cat, or if the pairs should be both of the sensors on one Bank. In other words, should I change both the Bank 1 sensor 1 and Bank 2 sensor 1 at the same time, or should I change the Bank 1 sensor 1 and Bank 1 sensor 2 at the same time?
Thanks
