Hello together, for some time now my Renault suffers from an increasing starting weakness. It is a Renault Scenic 1 RX4 with the 1.9 l dci engine (102 hp). The engine code is I think F9Q. In between there was a sawing idleness again and again. So all injectors changed. The problem has become rather worse. Can one learn the injectors? Or is that not possible with this engine yet? If maybe someone can recommend a software? Horst
