Hi.My 03 Mondeo TDCI 115 has started to missfire and run very rough when starting from cold. Upon starting which it does fine on the first turn of the key, the battery light stays on for a second or so, while this is lit the engine will not respond to the accelerator what so ever. Once the battery light goes off after a few seconds the car can be reved normally, but it's missfiring and juddering. If I try and hold the revs at say 2000rpm it will be like choking up on it's self, the revs will be stuttering and dropping up and down and I'll get white smoke coming out of the exhaust. Once the cars been running for a few minutes it starts to clear it's self up, and once it's running normal after around 5 mins or so, it's fine, up until the cars left to go fully cold again.The car does not put out smoke if just left to idle, or reved lightly, just if i try and keep it at a certain rev range. Thanks
