ef engine light

I have a 1990 dx hatch with duel injection. engine light comes on after 5min ecu flashes once = o2 sensor. I replaceed sensor and reset ecu ran 10 15 min, light came on. dropped the cat to see if it was clogged, cat looks almost new inside and i can see right through. I pulled the plugs checked them all and they look good, a little bit a white. plug and wires are new, new o2, no weird smole or anything thing, once and a while i get an rotten egg smell. I checked the egr valve and it moves nice and free. ecu still blinks 1. Any help would be great.
