Basically as the title reads, was blowing abit of smoke under boost before but now blows smoke just idleing, and just recently started blowing a constant display of black flakes.
I've changed the oil, oil filter, fuel filter, o2 sonsor, flushed the cooling system, changed the spark plugs, cleaned out the AFM with the correct AFM cleaner and now running out of ideas, so if anyone can help that would be greatly appreciated, I've also had the ECU checked and came back with no errors or problems, it is running rich but both I and the mechanics are unsure why.
