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?

OK, I am an idiot. I re searched and came up with some info. Seems its the Bank2, upstream O2 sensor. Im off to Autozone for the new one right now! Add that to the struts, rear srpings, trailing arms, and A/C work that needs to be done, sheesh!!!!

Lean codes can sometimes be a result of vacuum leaks. It may be a good idea to check hoses and connection. Listens for hissing sounds. good luck Dan
