The cable between the accelerator pedal and the linkage is also referred to as the Bowden cable. I found the archived Braingears site, and it has a procedure but it involves adjusting it inside the cabin and is very cryptic (at least to me) as to how to adjust it. I am planning on lubricating the linkage, as it does seem a little dry. I agree with you, I am hesitant to adjust anything until I know what I am adjusting. But its a little dangerous at this point, as it sometimes dies when I pull up to a stop sign or red light (the microswitch signals that the throttle is closed so that the IACV valve can moderate idle). My wife drives my car a couple times during a typical week, so I am anxious to get this fixed.
