My car is running great, no issues. I just changed the ignition coils, i was having a misfire. It was easier since i was changing the back to replace them all. My CEL and VSC went on and it is code P0430 bank 2. Before i spend a ton on a new catalytic converter i would like to change the o2 sensors. Problem is, i am not sure which ones to change or where to start. Is this even something i am able to do. Thanks in advance.

 

I have the exact same problem. GS 400 1998. 180,000 miles.

I can't wait to hear a response.

 

In order to be helped as a rule of thumb always list the year of your car and model.

So what year RX do you have with this problem?
