Potential Ford Focus injector issue
The engine occassionally has what I can only describe as a 'hickup' at about 1500 RPM - feels slightly like a misfire on the injectors, but as it only happens at those revs - could it the fault be with the pump, rather than injectors?
The other running issue is that the power from very low rev up to 1500 RPM is low. When I asked my Ford garage, they reckon that although the injectors can wear, and may need reconditioning, the pump will either work & pressure correctly, or fail.
Also, I have now noticed that this issue doesn't seem to occur if I keep the diesel tank half full or more.

Well have you had the engine undergo a diagnostic check and did it show up any fault codes?
Other than that it could be a number of things - hence the diagnostic check.
Would suggest that you check carefully all air/vacuum hoses for connection/splits, also check the wiring to the MAF and also the inter-cooler sensors.
As for the injectors they would normally need servicing at around 100k mls so if your mileage is around that mark you may well want to have them removed and checked/serviced
