I have just replaced my injector pump, the new pump shaft wasn't locked when it was taken off and therefor i had to turn the injector pump 1 tooth at a time to time it up. It is running now and it will idle fine but when i rev it up and let the throttle off again it runs lumpy and sometimes stalls anyone know what this could be, oh and i have tried a tooth either side of where it is now and it is the same. Any help is much appreciated as i really need some transport tommorow. Cheers.
