When starting up from cold it revs up to about 2500rpm and stays around that mark for a few seconds then dips to about 1700rpm. It sometimes dies down to about 300rpm then spurts into life up to 2500+rpm. Ive stripped and cleaned the idler and its improved to this condition. It was much worse at one time. Once warmed up it stabilises at 900rpm. Any ideas anyone? Its been chipped, remapped, bigger injectors actuator etc
