2000 Lincoln Navigator V8 Four Wheel Drive Automatic 97000 miles
My Navigator runs fine, but the service engine soon light came on, went doen had the OBD read and it came up P0171 and P0174 OBD codes system too lean banl 1 and bank 2. Any suggestions? Replace all o2 sensors? Replace exhaust system, as I know it leaks moisture when left idling.
