ok so i have an 03 acura rsx, with a Cold air intake, when i turn the car on and start accelerating, theres this really loud hissing noise, and its normally there isnt this loud of a noise and when i brake, the hissing noise sounds like its being muffled, and when im stopped theres no sound at all, also after 5 mintues the noise goes away and it acts normal, i just want to kno if this is some major problem, thanks
