Symptoms of bad O2 sensors?

I'm trying to see if one of my O2 sensors is bad. My car has a OBD1 ECU so I'm not sure if it will throw an SES light if one of my O2's is bad. My car has been running real rich and blows black smoke out the exhaust (more than normal) every now and then under WOT conditions. Is their anyway to check for a bad O2 sensor?
Thanks
Thanks

DOes the smoke only occur at WOT? If so, its probably NOT your O2 sensor.....
