I finally recieved the O2 sensors in the mail, and have replaced both upstream, and both downstream sensors. I made repairs to the upstream bank 1 sensor harness, as it was falling apart just past the connector. I also found fuse #13 in the underhood fuse box blown. I found out it controls the O2 sensor heater circuit, and if my understanding is correct, when the PCM looked for the O2 sensor readings, and did nto find it, it was generating my eng light??? I suspect because of the harness condition. The check engine light and all 4 codes have left me for the time being, meanwhile my car is on it's way to Ford for the harness recall. Thanks for the input. This is an awesome site!!!
