Check engine light just came on for my 2013 EL 5.4L 3V, P013A O2 Sensor Slow Response - Rich to Lean Bank 1 Sensor 2. Anyone had any experience with this code with their 3rd generation? I was thinking to just replace the downstream sensor is the best guess to fix. However I did see that potentially the fuel injectors might have something to do with it. My scanner says the likely problem is an exhaust leak. Any advice is appreciated.
