Engine shakes while starting and open clutch in first gear.

[306__xrdt]

Hi there

Sometimes when starting the engine shakes and when i drive in first gear first time there is no shaking but when i stop and do it again the engine shakes and the whole car shakes badly from en engine hmm..
Could it be the lower engine mount that is going bad?
I adjustet the gear bolt back off the engine and the gearing is a bit bether now but after a month driving the gar problem is coming back..
I have reading some forum post about lower engine mount that is bad after many years off some oil on it and dust and salt/water (norway use salt on road on the winter and that is sh..t).
So what could it be?

Thanks for info and cheers!
I could post a video when starting and driving first gear iff that helps!
