Has anyone experienced this problem: When cold starting, the idle is rough, and the revs fluctuate between 1000 and 1200 rpm's (At first, I thought it was purring!).
After it warms up, it idles fine. Jaguar say it is a software problem they are working on 24/7 (right!). Any feedback.?

Thanks,
dongee

Jaguar four litre V8 engines are programmed to run very rich until warmed up. I never had a problem with my XKR but it was an issue with some cars.
