Besides possibly needing a tune up with fresh parts (spark plugs, air filter, ignition wires) the most common causes are vacuum leaks (old rubber hoses crack, split, and don't seal well) or the Lambda system isn't working (first check the relay that supplies power to the Lambda system, they seem to have a high failure rate).
