Engine limiter??

I sat in my 320 today and slowly revved up (once it was warm) when I got to 4200 rpm there was a big shake. As I revved abit more it shook more, like a big misfire, the whole car wobbled, it almost felt like the engine tried to jump out of the car. Is this normal? Is it a rev limiter? Any ideas what would cause this please?

Have your motor mounts and/or trans mount been checked or changed since new?

To be honest I wouldn't know, it has done 145000 miles and I do have lots of receipts but none for an engine or trans mount. Would this be a symptom I would get then? I have a Zafira with a front engine mount worn and I can feel the movement in that when I drive but this is like a big lurch, never felt one like this before. Maybe it's because it's a bigger engine so it jerks more than my Zafira?

does it rev normally when accelerating?

how about with the clutch pedal pushed in or out?

my guess is it knows when you are sitting still. and of course, as others are saying - if your worried about the shaking part of it, then you might have worn mounts.
