ok now I know that it is an air pump with a leaking check valve.
where do I look for them, under the hood or under the car.
I will get some carb cleaner and take care of this as soon as I can find the check valves location.

I am a pretty good with repairs once I get to the right part.

Hi There,
The check valve is located just below& to the left of the brake booster.Do a forum seach type: How to replace the(p1416) air check valve.
Bill Curlee tells you what to do & Patches has a picture of the AIR valve.

Interesting ... I didn't know the codes changed in 2004. I guess as time goes on, more and more 2004+ Vettes will suffer from AIR check valve failures and we'll be seeing more P0492 codes along with the P1416 for the earlier models.
