C30 Engine : C30 2007 2.0d d4204t no injector resistance?

[Wants a t5]

Hi im currently chasing a issue with my c30 where it has alot of black smoke when wide open throttle, ive been trying to go through the list of causes started at the egr and blocked that with no difference, changed diesel filter and air filter, cleaned all sensors with no change. Im trying to check the injectors at the minute and cannot get a resistance reading from any of them, the multi meter is just staying at 1. Just wanted to see if im missing something wether i cant check these injectors like that or wether they are all faulty?
The car judders in 4th at wide open throttle but only in 4th the rest of the gears are smooth, im hoping thats related? Hopefully someone with more knowledge can shed some light

Thanks for your time

If i replace injectors/atomizer with new ones, do they need to be programmed in the ECU ? Talking about a d4204t engine. Build in 2004. Swapped all 4

The injectors dont contain a coil of wire they are crystal material.

sounds like a boost pressure leak somewhere..??

yes the code numbers on top the injector have to be programmed in.
