1988 Honda Accord Stalling at red lights.

My 1988 Honda with 205,000 miles has been a good running car. It is stalling at red lights. The tachometer goes way down to 200-300 rpm. This happens even when the engine is warm. It starts fine and the rpm goes up then falls back to about 1000 like it should.

I've kept the car in excellent shape and replaced nearly all the engine parts. That includes alterenator, distributor, wires, belts, brakes, clutch and seals.

I took it to a mechanic twice and I've been told there is nothing wrong with the car.
