The way you said diesel makes me believe its an oil furnace. You need to have it checked. The furnace could have a cracked heat exchanger or it could be caused from something simple like a bad nozzle or dirty ignitors. Maybe something more serious like a blocked flue. Nothing to play with in any case. You need to be safe and carbon monoxide is a possibility.
