If you can find the IAC valve(idle air control) on the throttle body-it should be replaced or try to clean..If you put in new plugs and they turn soot black in a short time period, you have other issues-possible internal engine,such as valve train problems, or a partial exhaust blockage, or the fuel your buying is not good...

i would think a plugged fuel injector on # 6 cylinder could be the problem,or a big vacuum leak at that cylinder
a valve burnt/stuck could be but you dont see much of that anymore
could be coolant leaking into cylinder from leaky haed gasket but you would have to add coolant every so often
i would check #6 cyl. spark plug after driveing around a while if it looks new, ie no deposits on it then an injector would be what i would change next
