I am assuming your description likely refers to the "home" or straight ahead position of your front wheels leave your steering wheel not quite centered. Generally this can be corrected by adjusting tie rod ends, one side out the other in (by equal amounts). Simply removing the steering wheel and repositioning it by one spline could make a larger adjustment than needed, with the offset from center simply shifted from one side to the other.

If you are referring to feeling something like a flat spot in the straight ahead position, from which attempting minor steering adjustments (such as staying centered in your lane at highway speeds) results in a notchy feeling movement and results in chronic over corrections, that could be caused by a defectively over tight steering rack. Mine was replaced, after a persistent effort on my part to have the problem first acknowledged and then addressed under warranty. The improvement with the replacement rack was remarkable. I don't know how common this steering rack problem was in HCH I's, but I did take note that beginning with the 2006 model year the steering rack was completely redesigned.
