Default weird noise on startup?

i started my car this morning, and right after i started it, it made a hissing sound, or "kssht" sound. then it idled normally but i pulled it back into the garage because im not sure whats wrong. i always get my oil changed at 3000 miles, but this time i went like 4000. do you think this is related to not changing my oil? has anybody had this noise?

Whenever I put my key in and flip it to ON, I get the noise almost everytime.

im talking like after you hit the start button, as it turns over, goes "kssht", then starts idling normally.

The noise is normal. It's the air pump kicking on for emissions. Don't worry about it.

Sounds like the airbox getting its first breath or two in. my car has always had what i call a baby spooling sound coming from the air intake that got more prevailent when i switched to various CAI's

edit: also, i just picked up 2 quarts of oil, and put them in. i started the car, and it didnt make the noise. does this mean my car is burning oil? there's never any pools of liquid underneath my car.
The S DOES burn more oil because of the way the crankcase breather w/ the PCV valve works. You need to check your oil often and NEVER let it get below 1/2 quart low. At last year's Fall Colors meet. one guy did big damage to his bottom end by being 1 and a half quarts low. BE CAREFUL!

My s2k make those hissing sound after starting up engine. I may be wrong but it
is probably a starter. Probably it is a whinning sound.
