Well... the problem with the cold start idle has persisting for a week now. The car, which had a lot of trouble starting, used to idle pretty well as soon as it fired up. Drivability was always an issue, hot or cold.

Now the car fires up on a crank or two, which is great. The problem is that it has a very rough idle and if I try and drive right away, it has hesitation problems as bad or worse than before. It sounds like it is missing terribly.

But that is only until the car is warm. Once it warms a little, there are no noticable idle or performance issues.

I also have a check engine light on. I haven't borrowed the reader to check where this is from. I think it is my catalytic converter efficiency issue.
