Unusual Sound during Idle

My 95 LT-1 Six Speed when idling in Neutral makes a sound like the a/c is cyling every say 5 to 10 seconds or maybe if the car had air brakes and the air tank was full and it was venting additional air pressure every 5 or 10 seconds. It idles fine, cranks without effort and runs fine. Just sounds a little strange. Worries me but not to much, should it?
Thanks

RE: Unusual Sound during Idle

If it is not your compressor, then it is the Secondary Air Induction pump running which has an electric motor to run the pump. [8D]
