HELP!!!! Power steering too touchy???

My 90 notch has 15:1 power steering rack w/new inner tie rods, outer tie rods, and stock PS pump and pulley. It was origanally a 4cyl so i really dont know if its a 4 cyl pump or 8 cyl pump.

to the point, it will swerve left or right very easily when steering. I mean like just toching a bit to the left or right and the car will move a good foot to either side. I wouldlike to have it rather tighter or stiffer as u would say.

Any recomendations on what i should do, maybe a different PS pump or different PS pulley?


thanks,
eric

its not unstable at high speeds, but it definitly is annyoing.My 01 gt wasnt like this, and my corrola is fine too. I thought my corrola was a bit touchy, but my stang is so much more, that corrola feels like a gem now.

I hope somebody has some idea on how to make it stiffer???
