Engine light on dash
I have a 2000 Windstar. 3.8 engine. The check engine light on the dash will not go off. I have reset it several times by taking the positive battery cable off the battery, but it persists on going back on. I have 105,000 miles on this vehicle. Everything seems to be running fine except for the light on... Any suggestions? I think it might be the oxygen sensor....Where is that located? On the exhust line? Please help or give me ideas... Thanks
