ok so for the past few months my car has been surging at idle and moving at low speeds that it can sometimes pull throu the brakes i have done fuel system cleaner and different grades of gas with no help.

next problem maybe about a week ago it was raining and my car wouldnt stop as quick as it normally would i just figured it was because of that the brakes were wet. but sinse then the brakes have been fading i guess you would say very badly the brakes still have life in then so i know thats not the main problem. then for the second part of this problem i noticed yesterday, when at slow speeds braking they tend to fade much quicker than at higher speeds, plus at slower speeds when braking or at a stop there is a loud hissing noise when brakes are applied, and the engine starts to sputter and surge at this time.

I'm going to guess that both problems are due to a vacuum leak in the booster of the power brake system.
