Mondeo Tdci 2.0 130

Guys,

over the last couple of weeks my car has developed a bit of a fault.

whilst coasting at any speed, the car judders slightly, every sort of 3 seconds, its a sort of cycle with power and then lack of power, when the power is "on" there is dark smoke coming from the exhaust, and then when the power is "off" the smoke goes, i have also noticed a drop in fuel economy and a slight loss of power......

my mate had a quick look and done a leak off test (i think that was what it was) and the 4 bottles filled at nigh on the same rate.

the injectors were replaced on the 24/10/13, before i brought the car, (this was confirmed by recipt and by the garage).

i have no dash lights on, and there are no codes showing

any ideas please

If it's like a surging on and off of the power then check the pipe between the intercooler and egr valve..... Had a split and caused that sensation with plenty of black smoke too

thanks for the reply Mcbain, i will get my mate to have a look at the hoses and see what we have got.

anyone got any other ideas to look for whilst its up on the ramp

thanks
