Tried asking in the RST forum but no luck.

I got a S2 on EFi and have been away on holiday and not used the car for 2 weeks. Now its developed a problem.

When i start the car from cold its runs fine and idles perfectly. When the car gets up to running temp it still drives fine but when i pull up to lights or stop it wont idle and stalls. so i have to sit there reving it at 2 grand. Ive cleaned the ICV out and that hasnt helped but dont know what it could be as it hasnt been used. Didnt have this prob before i went away.

any thoughts?
