In the process of buying a 99 TD5 discovery. In March the fella put it off the road to do the head gasket and the power steering pipe burst on the way home scunnered with it he parked it. i am in the process of buying it (worth the money) have it up and running ready for the test but the engine is running light as if it is getting to much air. It does not smoke and starts very easily. its just fluffing on tickover and is down on power when driving you sort of have to rev the guts out of it to get it to pull .... any ideas please
