04 350Z WEIRD CLICKING SOUND!

[EL SIX]

HEY MY 350Z HAS BEEN MAKING A WEIRD CLICKING NOISE WHEN I TURN OFF THE CAR. IT ONLY DOES THIS SOMETIMES. I FIND IT VERY STRANGE AND I REALLY DONT KNOW WHAT IT IS. ANY IDEAS???

THE CAR HAS 49K MILES. I DONT RACE IT AND THE ONLY MOD IVE DONE HAS BEEN AN INTAKE

You might be hearing the throttle chamber closing. If you have a friend turn the ignition on without starting and then turn it off and listen around the throttle chamber see if its the same noise. Just a suggestion not sure if its what your hearing though.
