I've had a '07 Road King for about two years now and have a question about the engine light. When I turn on the ignition light will come on for a few seconds and then go off. After I start engine and take off if I accelerate to fast the engine light comes back on and stays on until I back off of the throttle. After I ride awhile it seems to be better but the other day I notice while I was in sixth gear and doing 70-75 light was on again and stayed on for a while until I backed of throttle again. Is this caused by lack of pressure in tank or maybe bad fuel filter?
