As a precaution -- since this sensor is so close to the headers, I added the Kevlar aluminized shielding to the back of the sensor -- this is to help not only with the heat from the headers, but, heat from the SS Fuel line that runs right behind the sensor. Also, I'm going to 'immobilize' the sensor so it does not move around:
so, that should be a testable item now -- if the sensor did not fry from the heat ;o).
I'll give this a go, and should have my harness by Wednesday to verify if this does not fix it -- if after the harness it still does it, I do have a new flex fuel sensor to install -- glad I have that!
what is odd is the fact I tripped no DTC. I fill up the car after every drive so none of the fuel has been there too long. In fact, I drove almost all of the E85 out Saturday -- then filled up again (same place though). If water was in it, I'd expect to see closer to 100% -- going to zero is the exact opposite...
Good Youtube on flex fuel sensors:
