Hello,
I know there is alot of posts for this code of 1151 but when I was at Advance Auto Parts yesterday the guy tried telling me the sensor was doing its job by telling us it was running lean. He said the sensor was fine and said I didn't need to replace it. He felt there was a fuel injector not operating right or something that would mess up the fuel to air mixture. Thinking about going somewhere else to get this as its the 2nd or 3rd time this code has triggered. Does the sensor need to be replaced? Any insight on this would be much appreciated. Thanks.
