I must be a moron, I searched on this code and didnt come up with anything and I cant be the only one to ever see this code? Anyway, my 98 SVT is idling a bit rough and is a bit harder to start, nothing drastic gas mileage is steady at 22-23mpg. It threw a CEL so I stopped in at Autozone and they pulled 1 code, P1151. It was something like H02 indicating lean condition. So I'll assume this means my O2 sensor(s) are bad? Do I need to replace both? Anything else I need to look into? How hard are they to replace and is $140 for both(Bosch)parts a good price?
