Yeah, the colder the worse. The hole that the idle air goes through was so small that the IAC counts and the commanded idle air only matched up when the engine was fully warmed up. The counts just were a constant 300 until the engine got to maybe 150 degrees, then they started dropping.

No. Yes. I have the stop set so it is at the recommended IAC counts, I don't remember what it is like 35 or 50, idk. If I open it any more I get severe cruise-controlling. I figured drilling a hole would be counter productive. With the stop adjusted too far open, the IACs would still be at 310 during most of warmup. It would die putting it in gear not fully warmed, it needed more air but the IAC was already fully open. I was torn between drilling a hole and not drilling a hole. I had too much air at warmed up idle, and not enough at cold idle. It led me to do some thinking (I'll be OK) about what was different, and found how small the air holes were. Here are some better pics of the differences. The more metal that I ground away, the easier it was to tune.
