TROUBLE CODES

2006 Ford Taurus

Computer problem
2006 Ford Taurus 6 cyl Front Wheel Drive Automatic 76,500 miles

For 2 months my car has set a few trouble codes that all seem to be related. 0304(random misfires)
twice. Advised to change spark plugs, I did. Code P2270 (O2 sensor stuck lean, bank 1 sensor 2) has been set 2-3 times. Was advised that it usually indicates the sensor is bad. Code 0300(very simiilar to 0304, random misfires). The check engine lit has always went off after a day or 2. If I changed the sensor might that solve the other problems?

Regarding the 0300 code, I don't have 0316 in memory, so I don't know if the tech bullitin applies. My car's manufactor date is 11/05, so I'm not sure, and a Ford dealership would have to do it. Right?

Regarding 2270.I guess I can unplug the wiring harness and lube the terminal connections and check the wiriing for any visable damage before I would buy a new sensor. Is this correct?
