Starts normal,nice steady idle,shifts into gear beautifully. Take it out for a ride and after it warms up the engine randomly has a high idle that will not allow it to be shifted into gear . If I kill the motor and restart the idle is back down to where it should be.
When the high idle occurs blipping the throttle has no effect.No valve adjustments or any other routine maintenance was done prior to this when it started happening . Any ideas out there ? TIA
