Rough idle/ engine rocking

[Haydn]

When my 8v is on idle it is very rough and jerky. U can feel the whole car moving a little. Any ideas what this is. I was thinking that it might be the front engine mount but i think that that is moving because of the engine. Also the engine feels like it is moving. in any gear if u let your foot off the accelerator u can feel the car kind of jump!!!! any ideas would be appreciated.

Could be the front engine mount. Quite common. Does it judder when you pull away in 1st?

Look for scuff marks on the underside of your bonnet.
Get a mate to rev the car and slowly lift the clutch, look for engine movement.
Sounds like a shot front engine mount.
