Engine Misfire

Good Morning,

I am having some troubles for a Land Rover
Model:- LA-Discovery 3 /LR3
Engine:- 2.7 V6 lion Diesel
Here is the detailed diagnostics
The timing belt and fuel pump drive belt have been renewed for the 170 000 km service. After road testing, engine misfiring has been detected.
SDD has logged fault code P121A-00:- Cylinder balance, injector restricted with no further information available.

i have made a compression test all ok
all injectors are operating well.
please can anyone help me so that i can deliver this vehicle. Thanks

How can you tell if the injectors are all working well?
Sounds like a faulty injector. Check the leads first. Idea â€œThere are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely games”

Are you sure they got the tension of the fuel pump belt right? â€œThere are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely games”
