   Hi there, did you fix this in the end?? My Saxo is doing EXACTLY the same thing. It judders whilst in motion and when idle, sometimes the revs bounce. It tends only to happen once the engine has warmed up, going up hills or when travelling @ a constant throttle speed. Iv done some research and there is about 4-5 things it could be. From HT leads, LAMBA Sensor, ICV Sensor, Coil Pack or the Air Mass Sensor. Any ideas?
