Trying to get 2013 ST-S out for a ride, but got the Check Engine light and can not increase engine speed with throttle. Checked for error code and got P1614 "throttle idle position failure on throttle release." Engine starts fine, but is idling at 1750rpm. I took screws out of right side handle bar switch/throttle assembly thinking throttle linkage might be "bound up", but no better. Anyone with prior experience or fix ideas? I dread having to trailer it to the dealer 40 minutes drive away since I don't have a hitch or a trailer! (From everything I have seen about spyder problems on this forum is this a necessary investment as a new spyder owner?)
