Hi I need some help please, I am working on a ford ka 2009 1.2 petrol. I have some problems with the engine and want to look at the fuel trims but they are different from anything I have seen before. I can see Lamda intergration, is this where i should be looking ?, and what do I look for, all the cars I have worked on before where short term and long term plus and minus 25%. But this car I am lost. I have no fault codes, it feels like it is a misfire about 2000 rpm. I scoped one of the injectors today and the pulse width is jumping all over the place.
Any help would be much appreciated.
Paul
