From what I've heard others report, the most common cause of an
unintended WOT "event" involves the cruise-control linkage, which
jams when the grommet guiding the c-c linkage rod breaks (an easy
fix). You seem to imply it's not that.
Could it be that the throttle's heavy return spring has broken (or
come loose)? Also, is the nut at the end of the near end of the
throttle shaft tight?
Actually the more common breakage in the throttle linkage (has
happened to me and recently to my instructor's S4 at the Glen) seems
to be the small nub of plastic (at the bottom of the actuating
lever), which grips the end of the throttle cable. But as you've
mentioned, this event normally will leave the throttle closed by the
action of the return spring. It's possible that you've broken that
plastic nub and somehow have lost (or restricted) the spring action.
If the cable's plastic anchor piece is broken--the cable-end can be
re-attached to the lever using zip ties and/or baling wire. AFAIK,
parts for the throttle assembly are not available from AoA except to
replace the entire throttle body ($600).
