Leads and plugs have been changed. About 5 codes come up relating to do with everything coil packs but like I said only happens when supercharger sounding noise comes from the motor

I am with Mif. Sounds like a cam sync, with the exact same behavior I experience when I stipped a cam gear (that drives the cam sync).

Muzza, cam sync is the under your coil pacs on a AU V8. It is where your distributor would be if it where in an older car.
This is him:  Your best option would probablly to import one from the US and have a mechanic fit it up for you (half hour job). This one is known worker on our engines. http://www.rockauto.com/catalog/more...641&cc=1304435 Cheers Stu
