Hi, my car has started to slightly run abit lumpy, almost feels like a very slight misfire on idle, and when accelerationing seems to have a slight shudder, it's a 1.4 petrol  its had new coil pack and 4 new plugs. 

Any other suggestions? 

A slightly rough idle is a trait of the 1.4 MPI. It shouldn't do it when driving it though. Needs scanning for fault codes. You can buy cheap scanners on ebay - the U281 for example. The diagnostic port is behind the cubby on the drivers side. Pull the lid right down past its normal stop to access it.
