Car is 1996 Corvette with LT1 engine. Codes are P0131, P0134, and P1133. I plan on changing the O2 sensor but which one? I think I know which one, but just to be sure that's all I'm saying. Let's see if I'm right or wrong. Which one would you change? Do I really need the special tool? Thanks in advance.
What would you do?

My guess won't count on which one to change first but, I'd try the PO1133 code (HO2S Insufficient Switching Bank 1 Sensor 1) first as it may affect both sensors. Will you need the special tool answer is yes, and don't buy a cheap one.
