Is yours silky smooth or does it sound kind of make a slight put-put noise at idle and low speeds? My fit is my first new car and it kind of sounds like it has just a little bit of knock. Is this normal for a small engine?

 

sounds like a d15 singlecam 8 valve out of cx eg lol... other then that it goes DOOOOOOOOOOO with an intake and exhaust... but the knock you hear is normal . dont worry as u break it in you will notice it quiet down

 

Okie dokie. I guess I'm just paranoid, but I won't worry about it. Thanks.

 

It's the injectors.
