Re: Ford mondeo 2.0tdci hesitation 2500 rpm

All boost pipes OK, you can get it to jerk about with the car stationary, bring rpm up to 2500 it starts to jump around like a misfire and you get blue/grey smoke, if you accelerate hard it jerks about on overrun also, there's a bit more to the story as follows, the car has had an engine change, the original engine suffered from bore damage due to gudgeon pin floating in con-rod, the vehicle was driven like this for about a month, eventually 3 hyd rockers failed and the engine was popping back through the intake, the engine was stripped and found to be non serviceable and a used engine was fitted, this engine suffered from the existing fault at 2500 rpm and had low compression on one cylinder when cold and it was decided to remove this engine and return to the supplier, a short engine was then purchased and the original cylinder head rebuilt and fitted back into the vehicle, the engine sounds fine but this problem still exists,the first engine fitted was complete and had its own injection system, so to sum it up two engines with two different injection systems fault still present, must be something that has been used with both engines or possible PCM/ICM fault maybe? sorry for long post Andy
