    I know this is an old thread, but were you ever able to find a solution to the issue? I'm having a similar experience with my '11 990 Adv. The idle would increase to around 3k-4k rpm, usually during long downhill sections. Instead of slowing when I let off the throttle it keeps building speed and rpm as I'm riding downhill. When the road levels out, I'm cruising at 45 mph (3k rpm) with no throttle input. It happened a few times on a ride last year, then went away until it happened again last weekend.

    Hi there, sorry for the delay in replying, I was out riding the big girl in Austria :-)

    The problem turned out to be a faulty throttle position sensor (TPS) I replaced both an it sorted itself out fine. Let me know how you get on mate
    All the best - Martyn

    Ihad a problem on my -07 with intermittent high idle, up to 3-4 k rpm.
    I turned out that some shade tree mech had "adjusted" the stepper motor causing to get "stuck" once i a while causing my high idle.
    A bit expensive as the mothership does no sel the stepper motors as a spare part.
    Triumph does and it will fitbut, alas I did not know that then and had to fork out a king's ransom to change out the whole injection thingy.
