The pump IS a load on the engine. When you go to hard lock, the pressure rises precipitously. Many a modern car (I don't know, if ours are included) deliberately bump up idle speed if it detects that you're steering the car, so that you don't stall it out.
So yeah, when the load on the engine is high, it's "normal" to bog down the engine. Could your pump be an excessive load for some reason, or the engine a little weak? Perhaps.
+1 on fluid type. I'm dealing with a leak on an '03 trailblazer, different car obviously. The leak has nothing to do with the noise: when the fluid is above the level of the pump's vanes, it's quiet. Once it's pumping air, the noise pokes its head out, and becomes loader and loader the less fluid there is (and the more air it's pumping). So if there's fluid above the level of the pump, it should be quiet. If it's not, even with fluid full, then I like the theory that your fluid is too thin. Type F tranny fluid is cheap enough.
+1 on replacing the pump. You don't KNOW that it's bad for sure, but it's so so cheap, while you've got your hands in there replacing pressure lines, just swap the pump. I had a bear of a time changing the pulley, but, I didn't know what I was doing when I did my pump.
Anyone know if impacts are safe to use, to remove the pulley?
And, anyone know of specific symptoms of a bad pump? I know it works with a rotary valve and two outlets. When you turn right, it allows the fluid to go in one direction, to aid you in your endeavor. When you turn left, the rotary valve turns and cuts the one outlet off, opens another, and the fluid goes in the other direction, helping you turn left. Just wondering if when a pump goes bad, if that valve can get frozen, or start leaking, etc., all affecting how it helps you turn-- or maybe even ending up fighting you? [pure speculation based on what I know of how the power steering pump works, so guessing at how it might go bad]
Finally, the only thing I've ever done is the pump and the lines. Anyone know if there's anything that could possibly be a symptom of the steering box that's right below the pump? I just don't know what they do when they start to go, so just wonderin.

so I got home and start to look to drain the old out and found were the big leak was the non pressure hose was fine but the tube you hook the hose to was broke in two
anyways I got a new power steering pump waiting for me and I am going to replace the pressure one just to make sure so after this there should not be nothing wrong unless it something else
