This engine "da . da da..." noise happens when I try to press the gas pedal to gain more speed(a little bit aggressive), and I notice that this only happens before engine temperature reaches normal temperature. It looks the car is trying to accelerate, but couldn't make it, ​This bothers me several years.. Any idea what the root cause it? throttle body?

Thanks.

 

I would contact **** Wolf, of Law and Order fame. Your car is unique, not every car makes the Law and Order theme song sounds.

 

LOL!

anyway, I searched threads/youtube, it looks like it's an issue about timing chain tensioners. not sure how much cost to get it repaired, or just let it be.

 

It's funny how the site censured the first name of Mr. Richard "D*ck" Wolf.

 

Probably your TPS is broken - you have to do full diagnostic to be sure.
