Question about 2003 Land Rover Discovery
I was towing yesterday with no problems when suddenly the car would move forward but revs were high still. I switched ignition off & on again and it seemed ok so carried on towing - now it wont move forward or backwards.

The tranny may have an intercooler and the fluid levels could be low. Check your tranny fluid levels and inspect for leaks. This tranny cooler will be upfront and look like a small radiator.

The "lift off and it goes away" is the clue I feel. This eliminates engine out of balance issues and points squarely to fueling issues. I would say try a compression test (always a good first start before you try much else) but with plenty of power and no vibration except in the range, probably not a compression issue. So, what's left? Fuel or air is the answer. Check air inlet path is from air filter to turbo and (more importantly) from turbo to intake manifold. Check wastegate on turbo is OK - disconnect the wastegate (it's bolted on to the turbo) hose, then **** on the wastegate hose, you should feel resistance. If not wastegate aneroid has perforated. At this point, I suggest taking it to a LR dealer and get them to pull all the engine codes. If all OK, next step is injectors. It's a common rail diesel and removal is a bit tricky, but if you pull them out, you will often be able to see a single injector with all the carbon deposits around it. If all injectors look the same, suggest that at this point you need to take them to a diesel specialist for testing and calibrating. This process usually cures 70% of diesel misfire problems. The other 30% really requires specialist knowledge of your vehicle's engine.

If it's an automatic, then odds are the box will change before 4000rpm, though it does redline at 4800rpm. If you pop it in sport, you may push more out of the box before a change up.

Have you checked the oil recently? I'd suggest changing it fully rather than topping up, and checking for any signs of metal in the oil (the drain plug should be magnetic, but running the oil into a plastic tub then sticking a magnet in to the oil and waving that round should find any not on the plug. Lots of Metal = Bad.
