1997 Ford Taurus 6 cyl Front Wheel Drive Automatic 197000 miles
ok, I went to change the o2 sensors on my taurus. I went to autozone to buy the new o2 sensors. They told me there was 3 on the car. 2 up front and 1 behind th converter. While I was changing the (3) sensors, the one in the middle that I was changing, I happened to look over and up a little bit and noticed appeared to be a 4th o2 sensor. So now im very confuse which 3 are the o2 sensors, and what the other sensoe looking device is. How do I know which ones to change? What is the 4th device. Is there pictures anywhere on the net or a manual that would show me which ones are which? Im changing these because my exhaust system is coming out in puffs rather than just a stright flow of exhaust. I changed the mass air flow sensor, and that did nothing. What esle could be the problem?
