Renault Megane shuddering and central locks itself when setting off. Is this a bad earth?

I have a 51 (Sept 2001) reg Renault Megane. The other day the car started shuddering and shaking and sometimes when accelerating it is as if there is no power, or it is very intermittent. I've had this problem before and changed an Ignition Coil and that has solved it, however, now it has stopped doing that and other problems have started. Upon setting off, the car will central lock itself, and it still feel a bit ropey to drive. Not sure if this is connected, but I have also noticed that using the electric windows makes the headlights flicker/dim.



Someone suggested it could be a bad earth. I do not know what this is or how to fix. Can anyone shed any light on this?

The shuddering was most probably caused by a misfire and that may even be due to one of the coils getting damp, or one of the coils is on it's way out. It might be worth just removing the coils and checking them for any signs of damp. The central locking operating when you pull away is normal ! Renault fitted a system called r.a.i.d (renault anti intrusion device), this system locks all the doors once you get over 6 mph. It can be turned on/off by turning on the ignition and pressing and holding the central locking button, keep the button pressed until you hear a beep to signal the system has switched on or off.
