Does anyone know where they are or where I can find an exploded diagram of the engine? There are a total of 3. Dad found the one under the catalytic converter, but can't seem to find the other two. I'm in Pittsburgh and they're in Miami, so I can't exactly go out and look myself.

thanks in advance

O2 sensors should be located in the exhaust manifolds, or in the crossover pipe connecting from one manifold to the other.
