Dave Moss's car suffers a bit with idling from cold currently (well did when running last)
His doesnt have an ICV yet though, but will do shortly

Oz_rs500 does your car run an ICV, or does it rely on the timing alone to stabilise the idle from a fixed throttle angle?

Im sure if you can give some details about your setup, that Mark Shead will be able to help you, I would imagine he has more knowledge/experience of Autronic on the YB than anyone else on the planet!
