if you have a aftermarket intake, then it is the iac valve (or similar) opening and closing.

Is it quiet or loud? If your timing is well off you can backfire out the intake but you'll know if you do.

its quiet, can only really notice it at idle, and timing isnt out, has just been advanced to 14 degrees, and is still doing it.
