Heidi&Franny restored a Carrera some time ago and documented it on Youtube: https://www.youtube.com/playlist?list=PLESd2KXwHSVKKl3FxYSFB3rGKZTsfWpQp, there is at least one video working on a bad idle:

Not quite the same issue as yours, but it gives you a good overview.

Thanks for the great link to the manuals, and also the google tip on searching across forums for the problem. Those Franny videos are excellent, and I've tested vacuum and cleaned the ICV. I even bought a replacement ICV but it did not resolve the issue. I am going to check the mixture setting as mentioned above, and also review the other forums and will report back.

I found it interesting that the behavior in that other video I posted had the same issue as mine, even though he says it's normal. I know it's not normal because I have listened to plenty of 3.2 cold start videos on BaT in which the motor starts directly to 1100 RPM with no roughness.
