Throttle position sensor that controls the idle it can go into erratic operation of the idle going up high and low I'm not sure if that's your problem ? Could be your crank position sensor I would just go over everything think of every possibility and get back to us? Aside from looking at all the possibilities you might have to take it in and get diagnosed ?
