I have a 67 Mustang. We have rebuilt the control valve and replaced the idler arm. The car is very easy to steer left and a bit tight steering to the right. There is also something going on when I hit a small bump (ie a manhole cover). Its definitely trying to go left when the bump is hit. Adjusting the control valve doesnt seem to help. Any help would be appreciated.
Sounds like you're dealing with some bump steer if its pulling when you run over a bump. Like ryguy said, I'd have your alignment checked, and then maybe invest in some aftermarket strut rods that eliminate the bushing. As for the irregular steering, I'd check for kinked lines or obstructions.

The "adjustment" doesn't do that. Check the alignment first. If that's not the problem, then you'll need to go through the valve again.
