96 disco, runs great cold?
Hello, 1996 Land Rover Discovery, V-8, Gas, AC
This information is the same for driving or parked;
Runs like a charm up to 4,000 rpm's, until operating temperature is reached, then a smooth running max of 1250 rpm's, anything over the 1250 rpm's, the Rpm's are erratic self adjusting up and down around 200/300 rpm, Max Rpm's 2,000+/-, cylinders pop (internal miss) but it does back fire and last but no least while accelerating above 1250 rpm's engine and trans are out of sync-engine supplies power to a missing transmission, but hey, it does catch up!
Camshaft position sensor?
Crankshaft position sensor?
Throttle position sensor?
One of my Temp sensors?
Or?
After typing this the ECM popped into my head, ouch!

You probably will have a cam/crank sensor postion plausability fault logged but not setting a check engine light just yet. This sounds like a failing CRANK sensor. Any trans work done lately? check your reluctor ring to make sure no teeth are bent. Also check the harness to the crank sensor, could be oil/coolant soaked and cracking isolation may be shorting the sensor out.
Good luck!!!
Good luck!!!

Forgot to mention
When I said it was 90% gone the sensor cover and the harness had been sand blasted from years of being in Southern California. Of course the heat from the exhaust and oil soaking helped to make it brittle; the sand ate right though the metal mesh wire wrapping layer of the harness and cleaned most all of what looks to be a fiberglass layer on the sensor cover.
