That's exactly what I did. The entire house disappeared in the smoke!
I used SeaFoam Spray (not sure what the difference is with Deep Creep) to get a direct spray past the throttle valve, Stick the long straw into the throttle body past the valve put the intake hose back on, turn on car, rev to 1500-2000rpm and start spraying. turn off car and let sit. I guess this is a good way to get past the "dam" they were talking about in the earlier posts.
