Default Vibrations in the car, even when idle

So I have had this problem for a while now.. the car has vibrations and trembling, you can feel it best when you release the throttle at about 60kph and just let it slide.. but it's not something with the axle, because it also trembles when it's in neutral parked.. The gear lever shakes and jumps alot when driving.

My engine is running a bit rough on idle also, but i don't think it should tremble in the car even so...

I'm thinking about replacing motor mounts and transmission mounts.. But when you yank the engine from side to side, it doesnt' seem to give alot. And the problem doesn't really increase when you put your foot down.. I'm thinking when the transmission doesn't really have any load, it's more of a subject to absorb the motion of the engine and planting that to the chassis? Any help would be appreciated!

Replace all engine mounts (including snub), check/replace transmission/diff mounts, change spark plugs and see where you're at.

Yeah, the snub i bought some weeks ago.. haven't replaced it yet. will try during weekend, but i think the vibrations are from side to side more than longditudal.. spark plugs are changed.
I think I found out why it's idling rough though, when i unplug my throttle body it idles "fine" (its still in emergency mode of course.. but the rpm doesn't jump the same way it does, and it doesn't jump alot when i release the clutch and let it slide in 1st, 2nd or R.
Costs a bit of money to change all that, though..
Especially where I live, cheapest engine mount is about 130$, i need two of them plus two transmission mounts.. i don't have that kind of money right now..

You have the snub already so do it now and see if the problem persists. If it does, swap the motor mounts OR the trans mounts. See which look the most worn and change them first.

Hmm, yeah, just need to check pricing first, have to see if i can get mountings for my DCN box from the states.. my engine isn't sold over there, so no cheap parts for me
I'll do it when I get the time, hopefully tomorrow!
