I was driving my 1986 Range Rover classic 3.5EFI the other night on a 15 mile journey, about half way it seemed to be losing a bit of power and started to misfire a bit. This got worse as the journey continued until eventually it was running on what seemed like 2 cylinders. Managed to get it to my parents house and leave it there. Went back today, checked and pushed all ignition leads, oil was ok, water was clear so no gasket leak. Started it up, ran sweet as a nut. Went for a drive and noticed on initial acceleration would run ok, then hold back and then go again. As time went on the tickover got a little lumpy. Checked exhaust for emmissions, but seemed clean, but I did notice the exhaust gas was very very hot and would give you a nasty burn if you left your hand there. The tail pipe was extremely hot and dropping water on it it fizzled and evaporated away! I don't ever remember any other car being this hot. Could this be an ignition timing issue, or has anyone got any suggestions?
TIA
