G'day to all

My old faithful EA 3.9 TBI which was working fine has suddenly decided it does not want to maintain revs at any speed. It will not idle and it will not run at a constant throtle preasure. The only way it will run is if I gently tap the accelerator pedal but as soon as I lift my foot off or attempt to maintain the same preasure or attempt to increase preasure (without tapping) in a constant manner it just stalls.

Does anyone have an idea of what could be causing this?

Thanks
