On start up it sound like it's not fireing on all cylinders it stutters but only till it warms up say 5 mins or so so I'm thinking plugs,leads or the coil also sometimes a check engine light comes on but again after 5 mins or so it goes off , any help would be great cheers Andy

I had the same problem on a V6 vectra, it turned out to be a head gasket. Water was getting into the bores and covering a plug. As soon as there was a little bit of heat in the engine it would run fine, apart from massive pressure in the coolent system.

Have a "sniffer test" carried out so you know have more idea whats going on
