Got any fault codes?

The wiring loom for the injectors inside the engine is a frequent cause of intermittent misfire on the PD engines. After a high mileage, the loom becomes brittle and the connectors intermittent. Often, there is no fault code.

 

The loom is cheap and easy to change in-situ. Warm the new one before you fit it, so the carrier becomes flexible. Despite a sharp bend, it goes in without a problem.

 

200k miles is about run in for a 1.9 PD.
