Hi Chaps,

Discovery 92 200TDi  140K

Engine occasionaly looses power at low revs to the extent that it will
only idle and you have to wait until it will pick up again.( this
while its warming up)

I have changed the fuel filter and bled the system but does not seem
to have made any difference.

It happens mostly at cold or while warming up, once it is fully warmed
up it almost never happens (happend twice when guage had just come up
to normal position and then lost RPM as I pulled up at traffic
lights)had to let it idle at about 100rpm until it picked up again)

I have tried turning off the engine when it occurs and restart but it
takes alot of cranking gefore it starts again.

Once the car is at normal running temp I have no probs and it runs
fine, consumption is very good, no smoke,no exsesive oil use.
I am running on 20% veg oil but it was doing this on neat diesel
back in September then the problem whent away,now it has started
again.

Thanks all

John

Where shall I look next?
