flex fuel sensor
I have a check engine light on so I went to repair shop to get light turned off only to find that
there are two code faults, one is left bank is running rich and the other is flex fuel sensor. None of the mechanics at the shop had ever seen a code default for a flex fuel sensor so they called ford and ford said they have never seen a malfunction of this device. 650.00 part that sits on the fuel rail. So I am thinking that the fuel mix is being distorted by a dirty o2 sensor. Any advice or help would be appreciated. Help Rich

The sensor is not mounted on the engine fuel rail. It is in the fuel line down near the left frame rail.
You may well have a problem with the oxygen sensor but I would get the problem with the Flex Fuel Sensor resolved first before attempting to fix it. Getting the mixture straightened out MIGHT take care of both issues.
