Engine Performance problem
1991 Nissan Skyline 6 cyl Two Wheel Drive Manual 150000 miles

I have a 91 nissan skyline gtst, thats been having some bad engine problems for the past couple months now.
They are: rough idle, engine always sputtering, black smoke out the exhaust, bad gas mileage, loss of power.
It doesnt really have any other symptoms, but this is really starting to frustrate me.
Ive checked the fuel filter its fine, as with the spark plugs, ignition coils, maf sensor. Im going to replace my o2 sensor soon, but I have a feeling that wont fix the problem.
Im really running out of options and where I live, theres really no where I can take my car too to get it fixed so its a do it myself thing.
Anyways, hoping someone can help me please. Thank you.
