I have a problem when slowly accelerating at arround 1800 rpm my car (kia sportage 2007 2.0 crdi) can start severely stutter. Only feelable with slow acceleration. Sometimes it holds back and suddenly accelates while maintaining low acceleration.

Anyone who can point me in the right direction? Tried kia, and another garage, they both cant find the problem
