97 Taurus Running to lean or o2 sensor??
97 Ford Taurus. Check engine light went on. Went to autozone 2 weeks ago and P0133 came up - Possible 02 sensor or fuel system running too lean. Then I go back today and another code comes up. p1131 - says that its running to lean. Is running lean my only problem or should i replace the o2 sensor?? I need direction!!! What to do first!?!?
