Anyone had a 2013 and 2014 Rogue?

I got the 2013 Rogue last April when my 2004 Murano died. I was pretty pleased with it, although always felt like it was a bit of a step down from the Murano. Anyway, when the 2014 Rogue was unveiled I was simultaneously pleased (that Nissan addressed every single thing I didn't like about the 2013) and disgusted (that it was the model right after the one I bought). My inlaws got a 2014 Rogue a couple weekends ago and when I was able to see it up close, I had to take the plunge. So I traded my 2013 for a 2014 last weekend.

So far I'm loving it, but I do have a couple minor concerns. I've noticed a vibration in the accelerator pedal that I didn't notice with the 2013 version. It happens mainly when RPMs are around 1750 or higher, even if I'm not pushing the pedal (i.e. RPMs rev up to 2000-2500 when coming down a steep hill). Also, it seems to idle a little rougher than the 2013 version.

Has anyone else noticed this? Any ideas on what might be causing this? Do I need to be concerned? Thanks!
