Hi not sure of engine size sorry,

Its a 2009 common rail diesel.

The car runs great with plenty of power.
However when you drive at between 1200 and 1800 revs under steady or light acceleration it will occasionally momentarily loose power just enough to feel it has actually happened. Sometimes it will do it more times than others and I have noticed it seems to be at running temperature before it will start to happen.

There are no codes and cant see any drop outs on road test with solus. Altho I cant see tps on this.
It has had fuel filter changed with forte conditioner added a few weeks ago.

It feels to me like the car is momentarily retarded or injectors switch off but only for a split second not long at all and then it may do it again a second or so later or not at all???

Any ideas or help would be very welcome..

Regards Brad
