hey my 05 loses power steering at lo rpm and at idle, i've already changed the pump! anybuddy know wats up?

 

Could be an issue with rack and pinion steering unit, I have heard these are notorious for leaking, as a matter of fact my 05 has a minor seap on both ends, the boots are slightly wet, but has not effected sterring response as of yet.

 

did you flush out the lines?
and check for a leaking rack by looking at the boots
