Oxygen sensor
You have a 91 Chevy lumina as it has on the manifold something that look like a spark plug but it is not as what is this and what does it do when the car is running or driving it?
I believe you are seeing your Oxygen or 'O2' sensor. It measures the ratio of oxygen in the exhaust and sends the info to your car's computer while you are driving. If the O2 sensor is bad your car can run poorly. It is one of the more important sensors on you car.
Where is the O2 sensor and crank sensor located on a 91 Chevy Lumina 31L and is it fairly simple to replace yourself?
I have a 92 lumina with a 3.1 and I found the crank sensor to be located on the passenger side of the engine in the back of the engine NOT on the side of the engine below the knock sensor. Hello, in my experience, all O2 sensors are located in the exhaust just after the manifold. It appears easy enough to change. If it is the crank position sensor you are looking for, take a look around the main pulley at the bottom of the engine, you may see a square-ish component located close to the actual pulley wheel, this would be the crank position sensor, it should have wires connected to it.
