Do you have a star machine? There was a similar issue with early 271 engines and the remedy was to raise the idle speed, also reset self adaption values. Moving away from that. Is the fuel filter recent and fuel pressure ok? Also, slightly more serious, I have had a diesel car having a similar issue and that was caused by the torque converter. Hope something here helps

Also, are all air vent pipes ok at the side of the engine block?
