Ok, I just took a video of start-up.
After I started it, I took it off fast-idle, revved it, then when it went back down to idle it stalled. The car usually smokes more on start-up.

Edit-Here is another taken 10 seconds after start-up. There was blue smoke in the sun. Then as fast idle is automatically taken off, it stalls. A second or two before it stalled, the smoke went away. So that's about 20 seconds of smoke.
