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?
