Hi there, My np300 is an auto, it accelerates very slowly and then all of a sudden loads of power, it's very annoying because you have to put into overdrive every time you want power, if you don't it's really slow to respond but when it does its fine, if anybody has any ideas I would be grateful!!!!
 
A few suggestions... How new is the fuel filter? Most diesel's including the NP300 are fussy about having a reasonably new one. Check the turbo pipes for leaks. You can normally spot a leak by a tell tale oil stain. Often injectors can get gummed up, so running some injector cleaner through the tank is never a bad idea. Cleaning the mass airflow sensor with MAF cleaner would be advisable too.
Thanks man, will do these things and see how I go, much appreciated!!
