your throttle cable is probably sticking..replace it.

check everything related to the throttle system. check for anything that could be catching on something, when the throttle is in movement. my throttle would stick only at wide open. needless to say a scary experience. turned out to be zip tie catching the throttle, on the windshield side of the throttle body. if you cant find the problem, try cleaning out the throttle body with some carb cleaner.
