Hi everyone. Found this board and happy I did. Anyway, I need help. I need to replace the oxygen sensors on my 1997 Concorde LX, 3.5 ltr. First time doing it with this car, although I've replaced these before with other vehicles. Does the 1997 Concorde have one before and after the Cat.? Also, how many wires are on each? I've found a place that sells single wire OEM but I can't take off the present O2 sensors to check as I need the car to get to work.

Any advice? Any other place I can check this out or does anyone here know this answer?


Thanks for taking the time to read.
