Like many others I've got a ticking sound coming from one or more injectors when accelerating. The sound suddenly stops at 3000rpm. There is no sound when you keep the same speed or when you're very gentle with the throttle.
I've listened to the injectors with a long screwdriver and nr. 4 and 5 are making more noise. I've got no problems starting the car and a injector return test does look quite normal.
When I disconnect injector nr. 4 the car keeps running, when I disconnect nr. 5 the car stops.
Is there a way to tell which injector is fault?
