I think that just reduces HCs in the long run of the life of the car, But it may help. I dont know when the vaccum switch is open, But i think its just when the car is cold or ot. One of those two. Its temp related. I would say check the output reading from ure 02 sensor with a voltmeter, and then replace it if neccesary.
