Wassup guys I dunno If this is the right place to post this. I have a 2002 z-28 m6 and every morning, when I start up my car and after warming it up for like a couple of minutes I hear a pressure relief valve going off, like a blow of valve for turbo charged cars but not that loud. I was just wondering wat it was, a/c compresor? air pump? wheres the air pump located? thanks in advanced.

It's the AIR Pump - it's located behind the front fascia - if you have an aftermarket air lid with the little K&N filter on the end of the line that used to go to your stock airlid the sound is more pronounced.

Thanks, sometimes it makes funny whining noises but after it reliefs pressure(blow off) the whining goes away but thats only sometimes, could the air pump be goin bad?

The pump will cut off after a few minutes. It's probably normal.

What is the fix to this problem? cause my car is still under warranty.

I doubt there's a problem with the system, especially since your car is an 02. You'll be able to hear the pump for a few minutes, that's normal. Mine makes the same sound.
