Bad TPS Sensor? High Idle?

Ok, so my 5.0 efi has a wierd idling problem. Fuel pressure is normal. When I trun the steering wheel (I have power steering), my idle goes down low, about 500 rpm, in threat of dying. But normal idle is around 1000-1200 rpm which is high, whether I am parked or at a traffic light. The rpm goes up slightly when I release the clutch which seems to be a throwout bearing in the trans. Anyway, my throttle isn't sticking open. The idle is pretty constant, just high.
