ZR 1.4 - Uneven Idle?

Hi All,



Wondering if any of the gurus can help!



A friend has brought over a ZR 1.4 petrol, which has an unusual, uneven idle. It's as though the car is chugging while on idle. It's not serious, but definitely noticeable. The plugs all look ok, and I have swapped the HT leads with my ZS and it didn't make any difference. Any other ideas what could cause this? The car is on 60k miles now, with a full dealer history, so it's been properly looked after.



Cheers,



Wigster.
