Idle is funny when cold, but is otherwise normal

[JwUoNoG]

When I start my car up, the idle is very low, and it stalls. I adjusted my BISS to increase the idle speed, but eventually, the car still drops down, and shuts off. For example, last night I went to start the car, the idle was about 500. I adjusted it to about 800. I got back in, every 10 seconds or so, the idle would drop about 50 rpm, until it eventually shut off. I turned it back on, the idle is "normal", which in my case, is surging(1200-1500), or at 2000 rpm.

What is it that's causing my idle to die when I first start it up?

The first thing I would do is check your ISC coil resistances. It also might be a dirty throttle body or vacuum leak.
