Hello, this noise has been found to be a problem is many of these engines etc.. Mazda determined it is from a misdesigned IAC or idle control motor on top of throttle body. Mazda redesigned the IAC and has new part #. The IAC sits on top of the throttle body and controls air intake etc to controll various idle speeds etc. I would call local dealer, ask for updated IAC and part 3/price.This is most likely the cause of the noise you hear
