There are two oxygen sensors in a 1992 Mercury Grand Marquis. ON one the left bank of the y pipe and one on the right bank. Use caution when removing them. Often times they are seized in there and lots of damage can occur when trying to remove them. Let the car warm up alittle to ease with removal but be careful not to burn yourself.
