just wondering if anybody has had the same problem, when the car is left standing for a few hours or overnight,when you start it,it splutters for a few seconds and throws a load of petrol fumes out the back,then clears after a few seconds,its a brand spanking new fully rebuilt engine and not even run in yet,its definatly the injectors leaking off ive had this before on a rs turbo, will fitting new injectors cure this? or is there something else mite be causing it? any ideas guys?
