Where is the Oxygen Sensor on a 1995 Buick Skylark GS?
Usually between the engine and catalytic convertor.
just beneath the headlights to the right of the do-hickey thingy and kitty korner from the widgity whatsamacallit.
On any engine the oxygen sensor or sensors are always on the exhaust between the manifold and the cat converter. You have a V6 so you're gonna have two of them. They're easy to spot because they look kinda like a spark plug only with a regular looking wire coming off of it. Dodge Man is right though. Soak them with a penetrant to loosen them.
It's most likely on one side of the engine exhaust manifolds. It might be covered with a heat shield. Or if not, it probably would then be towards the center of the exhaust system further down from the engine under the car screwed into the exhaust pipe.
But I would have the engine codes read first to determine what the computer is saying the problem is. Remember that the computer uses the o2 sensor to detect problems, so if the computer indicates that the o2 sensor is detecting a lean or rich condition it's probably another part on the car that would be making the exhaust not meet the requirements of the emission control system. (most auto parts sales people like to sell o2 sensors to people who know nothing about the car because it's easy to convince you that you need one, and for 50 or more dollars it might be worth looking further into the problem)
on the head pipe between the exthaust manifold and the converter
