If the O2 sensor is bad, it can cause the engine to run very rich. However, and rich running engine can cause the O2 sensor to fail, so it can be difficult to find out which caused which.
the o2 sencor code but is blowing this wet black smoke, smells like gas out the pipe. and the plugs arent wet
theres no water geting used
its running too rich if its fouling out your plugs. try a hotter spark plug and see if that helps.
