Ok so I recently found I have a small powered steering leak under the car there is a rubber hose that is just deteriorating after 10 years. Then the other day I noticed that when I turn the wheel it's making the rpms jump substantially. When idling at 500rpm it can jump up to 1500 and sometimes 2500 rpms when I turn the wheel. The worst part is when I'm driving in first gear and turn the wheel because it accelerates the car forward. Any idea what might be causing this thing to jump that much. I was thinking either the switch attached to the p/s pump or possibly air in the line? Any help is appreciated. Thanks.
