1989 Ford F-150 Custom 5.0L Runs Rich
Posted to Ford Driveability on 3/9/1998

I have never had a Ford with this code. I have talked to Napa Tech and they said if the reference voltage is Ok that it had to be in the eca. There is no real test to check this code so if anybody has ran into this please let me know.
