1.4L making weird noise and vibrations...

[MachineGun]

Hey guys!

Went through this whole site and still can't find the issue I am having.

I have a 2013 RS auto with 23000 miles. When I press the gas and accelerate I hear a dirtbike sound(serious) in my engine which vibrates the hell out of the dash. The sound is not present when I am at idle and press the gas. Also no check engine light.

Seems like it started happening after I had my waterpump replaced at 12000 miles.

I am unable to catch the sound on video.

Any ideas before I take it into the dealership.

Never heard that on my 2013 LTZ..
That is an odd one for sure. Without the dash vibration, it almost sounds like an exhaust manifold leak.

I'm unable to find the threads for you now but search intake manifolds on here, I myself and a couple other people have videos. Listen to 'em.

The sound happens at 2000rpms evertime it runs through the gears. Funny thing is I never hear my turbo spool(?).

I have checked the manifold, air box, and cv boots, and anything that could be loose.

Other than that the car runs smooth on the freeway and still no engine light.

I have also been using Shell's 91 octane since I bought the car a year ago.

Any one have this problem…? For a while now when driving down a road that isn't exactly perfect the car makes not a rattling noise and not a creaking noise, but almost like something is bouncing around. Now the weird part is what has started recently.. when I pull up to a red light or stop sign and my car is idling, periodically it starts rattling really loud. I am not sure if this is two separate issues but I can't figure it out. I thought it might have been an intercooler pipe rubbing but I have all areas where it might start rubbing wrapped in a reflective bubble wrap so to speak. My mods are: TTR trans mount (and no this isn't the normal vibe that come with it), MPFab intake and anaconda (does not include heavy duty clamp he offers), and zzp exhaust.

I haven't had a lot of time as my semester is coming to a close. Also the noise is much more noticeable from inside the drivers seat. It fairly quit outside the car. Thoughts and opinions greatly appreciated.
