Hi all, as above really. I have a dilemma with regards my s2!

The problem is from cold or first thing, the car struggles to stay running and ticks over very lumpy, and cuts out if it isn't revved (coming up to give ways etc-not good ) Once warm, the car runs fine. Its running 803s, Level 6, Champion 59c plugs, a Newman cam with solid lifters/double valve springs (they're adjusted fine) Is there something obvious that I'm missing? Could it be cold start map???

When its revved from cold, its almost like its running on three! It revs erratically (sp) anywhere from 500 - 3000

Any help/advice/shotgun would be very helpful!

John
