I have a 1990 2.9L Ranger that has 268K miles on it and I know that the o2 sensors have never been replaced. I can only find one right before the cat. Is there any others on this engine or is that the only one. And since the vehicle is "broken in" could the o2 sensor go bad or malfunction without ever throwing a check engine light?
