OK, so I've had my RS for a few years and a few miles, but it has had a problem with the throttle bodies falling out of sync within a few thousand miles repeatedly. Finally after discussing this with my dealer, he figured out what has been going on. It turns out that the butterfly for #1 cylinder was hanging up in the throttle body. All it took was to loosen the screws on the butterflies, snap the throttle a few times, re-tighten screws and re-sync the throttle bodies!! It runs great now, better than ever! My hats off to my dealer, (Steve @ RPM Motorwerks in Belleville, IL) you the man!!!
