Ya'll fake news!
It's just the vacuum pump on the intake cam. Happens mostly to 2015's, those Spaniards didn't tighten the pump..
Here's a video re-creating the noise:

That sounds suspiciously like the fast clacking sound I heard as well.This is the exact sound I hear from mine. My car is a Cleveland built engine but the car is a 2015. Wondering if this is the problem on mine?

So what's the solution to fix this? Odd that I've only had it happen once so far. If something was loose, I would think it would do it more often.
I vote this myth is busted!! Thanks drewfis

Maybe. But I would think the movement from a loose plate would change airflow, which would result in a noticeable change in power--more like surging than a hesitation. I guess it could be mistaken for hesitation.Hey, TorqueMan...
Is the butterfly plate held onto the TB shaft with a pair of tiny screws like in the olden days?
Hmmm. I wonder what would happen if both of those screws were backed out just a hair?
Clicking? Check! (but admittedly not likely audible from inside the cabin)
Performance impact? Check!
Intermittent problem? Check!
Self-resolving? Maybe, but admittedly iffy.
Intriguing idea? CHECK!
Exactly the same issue here in Belgium with the COBB-AP.I just had this happen the other day getting on the freeway at the top of first gear. Not sure if there was any black smoke because it freaked me out and didn't look in the rear view. Never happened before, car has 23K miles, 91 Oct. Tune+, Sport mufflers - nothing crazy. Engine was fully warmed up, 1/4 tank of gas remaining and a hot day (95 deg)
Thought for sure I blew something... In my minds eye I could just see valves slapping the pistons. Drove home without an issue, listened with hood open and didn't heard any odd noises. Car seems fine and I've gotten on it a few times since and it hasn't repeated. I didn't have the access port connected at the time, but I'm sure it would have shown knock. I did go back to the Cobb OTS 91 Oct. tune the next day just for...because.
Mine was more than 4-6 clicks, it was more of a rapid fire loud metallic clacking sound that last a second or 2 till I let off the throttle.
Rattling is different from clicking. Rattling under full throttle is more indicative of preignition (knock). If you are getting knock while running a tune I would suggest getting that sorted ASAP, and I would NOT run that tune until you do. Knock is your engine talking to you—listen!When driving stock, there is no rattling sound at all on full throttle.
