93 taurus 3.0 runs rough after warms up to oper. temp

I have a 93 Ford Taurus 3.0 that runs ok when cold but gets worse when it gets up to oper. temp. It also blows out black smoke and wont get over 40-45 mph. I have changed the plugs and wires, coil, ignition module.I got one of the codes saying some about a HO2 Heater. I wanna say it was a 137 code will have to repost codes tomorrow. Could the heated 02 sensor cause one to run this rough. Thanx in advance for any help.

Yes a faulty O2 sensor can cause that problem.So could a MAF,MAP,CTS,IAT sensor or leakings injectors or pressure regulator.Give us the code and we can go from there.
