Is there some procedure that the ECU does when the battery has been changed? I put a new one on last week and the car's been running a bit lumpy since. ISCV has been unplugged as well, I seem to remember you have to sit there with it idling for 10 minutes??

Yes there is,cant remember what it is though,think you have to hold it at a certain amount of revs for a while then go out and drive it.
Someone on here will know,must be someone who has changed the battery recently

I thought the cure was just to drive it and it'll re-learn anything it needs to?
