I need to know what to do with the 2nd o2 sensor on the 2.0l engine for my 03 tib.
Need to know if i need a cat or not or if that would mess up my computer to run it rich.
Need to find out where to get maybe an o2 eleminator for the 2nd sensor

You will need to have that 2nd o2 sensor or you will not pass emissions testing. I had mine extended after a high flow cat.
