I'm trying to locate my oxygen sensor. If anyone nows where it is I need your help. I drive a 1992 acura vigor gs. Thanks

Locate the engine head. An exhaust manifold is going out of the engine head. There may be a heat shield over the exhaust manifold. Look over the exhaust manifold carefully, there might be a sensor (shaped like a cigarre, but shorter) sticked in there somewhere. It's an oxygen sensor. 1 or more wires should be coming out of it. If you cannot see it, just follow the exhaust manifold until you reach a catalytic converter. Oxygen sensor should be somewhere between the head and the cat.

On a side note, do not try to touch the exhaust manifold if you have driven the car in the past few hours. It gets pretty hot :D
