Ill have a look at that on eBay always come in useful in the future. Has a 52 plate Astra beryone coupe got the same engine in it as mine which is z22se as my dads got one and if it is I may be able to quickly change the coil pack over to see if that makes any difference
The Astra Coupe could be either a 1.8 or a 2.2 from what I've seen of them. Best thing to do is pop the bonnet and have a look at the engine. 1.8 will have the exhaust at the front, 2.2 exhaust on the rear.
