The car had a catastrophic power steering pump failure (pump tore itself apart left fine metal fragments inside what was left of the pump) installed new power steering pump. Now after the power steering fluid comes up to operating temp there is very little to no power assist while the engine is at idle, if the fluid is cold as when you first start the car the power steering works as it should. This is what I suspect, is that metal particles have gotten stuck in the vanes of the new power steering pump and as the fluid heats up the metal expands and the vanes and the pressure regulator are getting stuck so the system does not have enough pressure at idle rpm's (about 700-800 rpm's approx) to assist in the steering and I may need to replace the pump again to fix this. I have flushed the systems many times now. What do you think?
