is this a vaccum leak?

[propr'one]

When i rev my engine from idle, or from any RPM really, it sounds like there's a very sharp inhale. (think person breathing in hard) it happens for about 1/2 a second and then goes away. any ideas?

that's your car sucking in air from the intake...

fuel + air + spark = healthy car

i did think of that (obviously) but it sounds retardedly loud. i guess i'll just compare it with another 328. but thanks
