1994 Honda Accord Honda Accord Dies When Idle

I have a honda accord, '94 (224,000 mi), automatic and every now and then, when coming to a stop light/sign, the car will putt and sometimes cut completetly off. I've been driving with two feet for about 2 wks (one on the brake, while reving up w/ the other) to keep the car from idling so low. Since the car is so old, many mechanics can't test it on the CPU and Dad thinks I should add gas treatment/fuel injector cleaner once a week. I'm not sure if those things work. Is there a one-time fix for this stalling/stopping problem?
