Where is the oxygen sensor on 93 impreza?

On a 1993 Subaru Impreza, the oxygen sensor is typically located in the exhaust system, either in the exhaust manifold or just after the catalytic converter. For most models, you'll find it on the exhaust pipe leading from the engine. Depending on the specific engine type, there may be one or two sensors (upstream and downstream). Always refer to the vehicle's service manual for precise location details.
