That's what I was thinking. Without the spring, I'm thinking the weight of the linkages can cause the rack to move. I'm also thinking that might be detectable in the accelerator pedal. Does it move down slightly as the engine revs. Also, in a pinch, the problem might be temporarily fixed by attaching a cord on the accelerator which could be pulled up to stop the engine from accelerating.
