90 240 Wagon Run Problem 200 1990

Hi everyone,

My 90 240 has a problem, it starts fine but it runs like it has a miss and it blows alittle black smoke out the back and smells rich. The codes say it is the o2 sensor and something with the mass air senor, if i un plug the sensor it doesnt change. Is that good or bad? what should i replace?

thanks
