1/. the idle returns to normal after switch-off during fast idle.
2/. after a stall on return to idle the engine will sometimes only restart after turning off then on again. It seems the idle mixture is too lean for the engine to fire with the stepper stuck wide open and the throttle closed. It returns to normal when the stepper is reset. It happened as I negotiated a slow Tee junction during my last ride on the Trek and today there was FB post about a dealer struggling to solve it for a TRK 502. If it occurs again on my bike I will give it a fist full of throttle to see what happens.
