FT86 Idle Noise/Issue ? Injectors?

[Rezi]

Hello guys, (and girls)

Got this strange idle noise and sometimes between 2000-2800RPM while cruising (light throttle).

I know, this engine produces hell-a-lot noise.
But in the meantime i could seperate noises between fuel pump, direct injection etc.

It sounds like something is "slapping"? Only hear it after warmed up the engine (200°F). Build date: april/2012. Never had any issues with it. No idle dip etc.

My guess would be the port injector. What do you think?
And yes, i searched the forum with similiar(!) noises as of mine. No hit.

You can hear the noise better when the camera is moving behind the engine (usually where the leaking cam-plate is for MT)

Sometimes i hear it clearly, sometimes not.
Also i logged it with the OFT (port/di injection mode) and when looking for the spot where it usually occurs my bet would be PI. AVCS (intake&exhaust) also looks good.

Sure, i could take my car to the dealership, but they are not the same in term of warranty etc as somewhere else. Also charging me for "listening" and telling me "working as intended".

Does anybody has this similiar noise occuring?

(Excuse me if there are any typos. Writing in english is not my strength )

Take it to the dealer, there's a TSB on the fuel assembly. Although mine is still making a similar noise at idle
