They should all be about the same. That tells me that cylinder is not firing properly. Fuel, fire and air. Make sure that injector is pulsing fuel out properly. Make sure that spark plug is firing. Might also have a valve sticking open on that one due to carbon build up. Have you tried some injector cleaner? A can of sea foam to a tank of good gas will help clean the carbon build up if there is any.
