Hi guys

Between a mate and myself we have rebuilt my PD150 ARL engine.

It’s had new piston rings on original pistons, honed bores, crank ground, head skimmed. Turbo has been re-conditioned.

Tonight was the first start, it started after several cranks and idles fine. However it has a flat spot around 2000 rpm, it won’t rev and bucks/judders. No fault codes except the ESP light is on the dash.

It’s almost like it’s starved of air or fuel.

Injectors were re-conditioned 30k miles ago before the engine rebuild. We are thinking maybe dirt in an injector or it’s the loom.
It idles great but can’t figure out what might be wrong.

Anyone have any suggestions?
