,almost always simultaneously. for some reason every time i notice that the power steering is rough or goes out i notice that the spedometer isnt working as well (it sucks because sometimes i cant tell how fast i am going),but then ill be driving and making turn then the spedometer will shoot right up to the speed that i am going and the power steering will kick in.( im not sure if they have something to do with each other though. how can i fix this problem???PLEASE HELP THNX.
