Premium gas only, a tune-up with new plugs and 8mm wires for starters...for compression, check here: http://www.landroverresource.com/ and type "compression" in search block.

I would guess sticking or burnt valves...you are on the right track with a compression test (check compression when the engine is warmed up)...you might need your heads rebuilt.
