Hi all, i recently bought a 2003 1.0 arosa from an auction, its a very pretty car but has a got a problem, on tick over there is a misfire, i lifted the bonnet to see a spark from the coil pack to the lead so i replaced the leads, then the plugs, but it still misfires on tickover, it drives first class, no hesitation, bunny hopping etc, it cant be the coil pack as it would miss underload, it only does it on idle, any ideas guys., im flumped, thanks in advance
