  Sometimes when I start my mondeo (petrol), mainly when the engine is still warmish, I have to 'catch it' by dabbing the accelerator to prevent it cutting out. The battery is nearly 3 years old and I do a fair number of shortish journeys. I checked the water levels in the battery and toped them up
