Hi Guys
My Discovery 300Tdi has this annoying problem...
It starts fine Most days it is fine, but a long hill or an extended sprint over above
120Km/hr ( full throttle or high load ) and it starts to "miss", back off and it comes right, just like fuel starvationWhen it is missing, nothing obvious comes from the exhaust The water temperature remains normal The boost pressure and revs spike downward ( symptom rather than cause)
Some times it will go for days with no problems, this morning, fine going to work, hill at work - problems, coming home no worries.
The figures
1995 Disco 300Tdi with EDC ( auto of course ) 250k kms on the body, engine unknown I rebuilt the engine some 10k ago due to no oil pressure, dropped cam bearing.New timing belt of course, and injector timing since checked when I did the fan hub.
What I have done. Drained water trap - no water Fuel filter Cleaned that filter on the chassis rail, it was dirty. Opened tank and checked pickup and tank - clean.
What next ??? do these engines have fuel pump problems ???
Other than that the vehicle goes fine although last week a had a problem with not starting, sort of coughed and spluted but once on the road, no problems and all came good.
Thanks
