It just popped 3 codes up today. Lean on bank 1, lean on bank 2, and the 3rd 02 sensor is not receiving a signal. Its still runnning fine getting the same gas mileage as normal, same power, ect...
It has the vortec 4.3 and the only thing that i have done mechanically different to it in the past 8000 miles is I just changed the fuel filter correctly 2 days ago. No wires were messed with in the process and nothing out of the ordinary other than the codes.
Any knowledge on the matter would be greatly appreciated.
Thanks
