I have an issue with my V8, it had become an utter dog to drive, stalling at junctions all the time. I changed the plugs and they were all black I also changed the MAF, the latter had improved it no end, but it’s still missing a bit at idle, so I pulled the codes again, and got P0130 ‘pending’ so cleared that, let it idle a bit and checked the codes again, this time I got P0130 and P0150 both pending, repeated this and got just P0130 pending again. Is this just a case of waiting for the fuel trims to adjust to the new MAF? Or do I have duff O2 sensors
 
Decoding those two DTC's would seem to indicate problems with your O2 sensors, both of them, or something common to both such as wiring.
The plugs being black and sooty would also indicate an over-fuelling problem too.
These are just generic DTC's and not Land Rover specific but:-
P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0150 O2 Sensor Circuit Malfunction (Bank 2 Sensor 1)
 
Yes, I am aware of the meaning, however prior to this the car also had P0101 code and a whole host of other O2 sensor codes.im wondering as the MAF was failing if it pushed the long fuel trims so far out that until they adjust to the new sensor it will log these. I should really dig out the auto com and have a look at the live data
