Electronics are not my strength, but a year ago when I was shopping around for a SRT, a dealership in Nebraska had a silver sapphire SRT.

When I spoke with the salesmen, he had mentioned that service was fixing a acceleration issue. I had read about the IC pump issues, and assumed that would be the correct fix. However he had explained later trying to complete a sale (after my current purchase) that the accelerator pedal was in fact the culprit this particular time. It almost appears the pedal and sensor are one entire unit, but I could be mistaken.

Good luck with your search, maybe this will help justify your thoughts regarding this being a pedal sensor related issue.
