Problems at tickover

Hi.
I`ve got a 1998 1.4 corsa automatic.
It seems to be running very lumpy on tickover, if stopped in drive at a junction or at a set of lights the car is juddering all over the place, slightly better if i knock it into neutral.
all the obvious stuff has been done, new plugs and leads, new coil pack, lamda sensor etc.....it even had a new cam put in it as we found that to be well damaged even though the car has only done 46000 miles.
Any help/advise would be appreciated.

Thanks, Jayne.

Sound slike an electrical fault rather than a mechanical one, check all the plugs are in right, maybe try a spare coolant temp sensor first.

Thankyou, I`ll have a look at that. I forgot to say earlier that it`s better when the car`s warmed up a bit. When i start it first thing in the morning it`s terrible. It jumps all over the place.

Thankyou. Jayne

Only when holding it in drive at t lights etc may not be engine at all
the auto box have filters (in the pan at the bottom) if the oil has not been changed that regular then they clog and are worse when cold even stalling on very cold mornings which an auto should not do
CURE>
get someone to clean the filter and refill with fresh A T F

Thanks for the replies, after everything else we might have narrowed it down to a knackered cat, its being replaced tonight and I`ll also get the transmission fluid changed at the same time.
