Hello all.
I'm new to the forum but I've been following it since I got a 07 GT last year. I bought a new 2012 Skyactiv Auto in Dec and I have to say it's quite a piece of engineering. I've been very impressed so far however I noticed this evening while revving it in park after today's trip there is a very noticeable vibration with the engine between 1900 and 2050 rpm. It completely smooths out under and above this rpm but since this is the main operating rpms (95-105km/h) I'm a bit concerned. Is it possible this is the resonant frequency of the motor or just some vibration? Can any other Skyactiv owners chime in please? Thanks!
