Ok just noticed this. Not sure if it's when its cold or not. When going up in gears the car will have a large vibration from 3k - 3500 RPM and then will quiet after that in my GTS. Wondering if anything is loose or if there is something I can do about it. It seems to struggle a bit. I have been trying to get a video of it but I will keep trying. Its like the vibration is holding it back a bit but not like terrible.

Ideas?

 

Bump

 

I'm having this issue as well on my ix too anybody have any input!? Thanks

 

Jukebox have you done any suspension work lately like before you had this issue? I think mine might be the passenger cv axle

 

I just bought the car but from people tell me is that someone put an aftermarket suspension on it. Bump for help for us.
