2009 Streetglide, stock except for dual header exhaust and pro tuner. This has happened twice, once running down the freeway at 70 mph and again running 30 mph. The throttle becomes un-responsive, the engine runs at a fast idle, and the engine light comes on. No codes show up. I turn it off and it re-starts like normal with full throttle action. I'm guessing a sensor somewhere is about to go out, anybody had this problem?
