hey guys about 2 weeks ago my truck started smoking at idle pretty bad. i checked the ballance rates on the injectors and there was 2 or 3 out by 3 the rest were in the ones and very low 2's... i filled up with some sunoco gold diesel and some diesel fuel conditioner (i stopped running the conditioner for about 2 months) and it no longer has any noticable smoke at idle, but it does let out a pretty good cloud of black smoke when i stand on it (stock tune is currently in the truck) it seems to be getting better and better but very slowly. could i have had a bad tank of fuel or something? ever since i put different fuel in it has been slowly getting better. havent had a chance to re-check the ballance rates yet.
