i changed plugs and think it is from inside of engine.

Thanks.

 

The noise wasn't there before you changed plugs? Did you change the plugs yourself? If so, what torque spec did you use? Did you use anti-seize? Did you use NGK OEM plugs?

 

Noise was there before and i changed plugs at acura service

 

What did the dealer say?

So you've been driving it like that for almost 2 years now? Sounds like either a TB tensioner or serpentine belt tensioner.

Pull the serpentine belt off and see if the noise goes away.

 

Can't really hear anything on my end. Until you put it underneath the engine. Hopefully it's not a connecting rod or something that's lose.
