My '95 land rover discovery auto diesel with the 300tdi engine was sitting for afew months and when i got it going again its got this weird issue with the engine.
when you push down the accelerator the revs will go up like normal but will soon drop down to just below 1500rpm and stay there, no matter how far you push the peddle in it wont go any higher
it is possible to get it working steady but only if the peddle is pumped up over 3000rpm
Heres a video showing it:

I have fresh fuel, cleaned the sedimenter, new fuel filter, new lift pump, checked injectors were working correctly, usual exhaust emissions.
would love to get out driving again as its my kayak wagon, any help greatly appreciated.
