SMOKE AND STALLING

GMC Savana

2003 GMC Savana
Aside from stalling at idle and during slow turns. I've been trying to run the engine with some additives to possibly clean out the injectors. It hasn't worked yet and when I rev it while idling, sometimes when it stalls I see some smoke coming out of my air intake. I've taken out the filter and it doesn't smell like oil smoke or from burning rubber, anybody know what's going on? Could the ISC be shot? Any help is appreciated. Somebody is buying this in 2 days and I want to try to get it nice for them. Thanks
