Okay, so I need O2 sensors for my 1995 Mustang. I have a 6 cylinder and when I was looking sensor prices up online, it asked if the sensors were located before or after the catalytic converter. I have no idea which one mine is!

Does anyone know whether or not a 1995, 3.8 liter's oxygen sensors are before or after the catalytic converter or does it vary from car to car?

the sn95 had 02s before and after the cats u probably need the ones before! i think they are responsible for the main fuel ratoi
