I replaced the o2 sensor that is just behind the engine on the tail pipe. I have a reading to fix o2 sensor still. I bought another o2 sensor but I don't know or can't find where it goes. I looked on the cat. converter and did not find it. If anyone can help me find where to put it? please let me know. the car spudders as it accelerates. thank You

There is only one O2 sensor on your car and you've found it. What brand sensor did you buy? The buzz around here is that the Bonnevilles are not very fond of Bosch sensors. What was the code that you pulled?
