No certification here (not even any formal training in wrench-turning), so take it fwiw: the feathering that you have to do to the gas pedal sounds like a similar issue I had with the stepper motor (idle air control valve - iacv) on the side of the plenum chamber. When it goes, you'll have a bunch of stalling issues - I've become really good at keeping the engine running with my toes and braking with my heel, simultaneously.
Clean your iacv and make sure it has a good seal to the plenum. If you have access to another Disco, swap the actuators to see which vehicle keeps the problem. Looking at your sig, I notice you have a Chevy Astro - I'm pretty sure that the iacv on the Astro is interchangeable with that of the Disco (at least for a '95 Disco it is, but I'm not sure about what model year Astro - see

Good luck!
Are you running rich, too? That's another symptom.
