Thanks James for the offer but after ringing my local Vauxhall dealer to be told its £50 just to plug it in, i got a code reader of e-bay and reset it myself. The code reader only cost £33.00 including p&p so bargin and it works well now.
Just for info the codes that came up where
p0340 cam position sensor no signal
p1700 svs request via can
p0100 mass or volume air flow circuit low input
p0170 rich exhaust
p0353 ignition coil 3 incorrect signal
p0110 intake air temp sensor circuit high voltage
p0302 cylinder 2 misfire detected
p0303 cylinder 3 misfire detected
all these faults are followed by, not present. after fitting the new coil pack and starting the old girl up..
Can anybody plse tell me if i need to worry about these codes?

?
Thanks
Andy
