Help!!

Hi guys, when driving my car every now and then i get what feels like a couf from the car, i dont loose any power or revs, and it goes away. But i went for a run out the other day and it kept couf/juddering while driving. it does it only when driving. I dont get any fault lights or anything.
When i first start the car on the morning after a couple of seconds i also get a slight couf. can anybody shed any light on what the problem could be.

Cheers for your help.

my last Astra did that. Im afraid to say if it a petrol it could be the coil pack and you can not buy coil pack singly its a whole unit, could also be the spark plugs or the ECU if you take it to VX they wont do anything unless there is a constant fault light.

just if it is the coil pack i was cheaper calling the RAC out and getting them top order the part 1 working day and the price was fitted £70 cheaper than VX.

hope its not that.
but im not sure is your car is ever petrol?????
