I recently replaced a flex fuel sensor with a replicator and that seemed to work with the exception of the light came back on after restart. You can disconnect the battery and run all day with the light off but as soon as you shut down and restart in 10 seconds its back on.
I have driven in excess of forty miles with light on and with light off and the results are the same. I had some one come out and test the codes and the only code showing was the flex fuel sensor he cleared the codes with hand scanner and again upon restart the light came back. Anyone have any thoughts?
