May sound stupid but has the battery been disconnected ? if so can cause problems until driven for a few miles. The Corsa seems to be very susceptible to issues with a dodgy battery.

Not saying this is your problem but it was on sons girlfriends Corsa SXi. New battery and drive round and all was sorted.

If it is starting ok then I would think the battery is fine and won't need changing, sorry about that.

Ok, heres my guess, the inlet manifold studs break of/ come loose and let loads of air in. A physical grab of the manifold sometime tells.

With the misfire codes then a stupid question, spark plugs, leads and Dis Pack , in that order.

Not sure about the Corsa C, but the Corsa B's where prone for Lambda Sensor (O2) fails over time, causing the ECU to having to re learn to the extent it would run rough / missfire on idle, worth a thought.

Does it run better after a good Italian Tune Up / Thrashing?
