i've noticed when i come to a complete stop, my car sounds like it is releasing a burst of pressure (like a blow off valve on a turbo car), but no turbo under my hood. just wondering what it could be...
coolant level was a little bit low, but hardly added any could it possibly be a leak? but how does that explain the pressure sound? and yes it sounds like it coming from the engine bay.
idk if the CCV has ever been replaced; the car has 228k miles and i do majority of shorter trips in the fall and winter because i am a student that drives to campus 4 miles round trip.

hahaha i bought the car with 119k so i really have no idea what has/has not been replaced, i just assume nothing has ever been replaced... the only time i can fix things is in may, but for the time being i am just figuring out what exactly i have to replace. i am going to do a coolant sysdtem overhaul and CCV in may.
Mine has been doing this since I bought the car... I never gave it much thought because I dont hear it most of the time when the radio is on. Do you know what causes it?
This would be easy if your car was turbo or supercharged because that sound 99% of the time is a boost leak! lol. So maybe you have a vacuum leak? do you have loss of power?
hahaha yeah, i guess if i dont figure out what it is i'll just do the same, but it's still weird and doesn't make any sense...maybe over the spring when i replace my CCV i'll figure out a logical explanation for it, until then thanks for everyone's help. cheers.
Might be a leaking check valve on the brake vacuum booster. If you shut down the car and wait until the hiss goes away, do you still have brake assist?
With the car parked, try doing a "bounce test" on the front fenders on both sides. A hissing sound, like releasing pressure, over small bumps or abrupt stops, was a warning that my front left strut was blown.
its not the struts; it only hissees when i accelerate from 0-10mph or come to a complete stop
