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.
