power steering issue

[malibuguy]

long story short, my car sat for 2months waiting for the transmission to be rebuilt (with an LSD yay)

When I put the car back together, I was not thinking ahead and hooked up the battery with the wheel slightly turned.

So naturally it assisted in odd steering positions.

I yanked the PS fuse, made sure the wheel was dead straight, and plugged it back in. And its better, BUT

coming back to center (from either left or right) it over assists and then goes the opposite direction. Does it regardless of vehicle speed. Its very strange and actually will pull out of my hand sometimes when I forget to use both hands. I have to drive with 2 hands pretty much all the time with a firm grip. ITS NEVER been like this in the 9 years Ive owned the car.

And because of other things, Im back to DDing the car atm so its really bothering me. I almost hit a car yesterday as I was steering around some joggers and then it whipped towards the opposite lane as I was coming back to center.

Before anyone says anything I did verify the alignment was dead on, I actually dialed back the amount of toe out I normally run (now 0 toe) in an attempt to numb it a little, absolutely no difference. I even drove around with the PS disabled and it does not do it at all, its definitely a PS issue, not mechanical in anyway.

what am I missing?
