I have a 2001 Holden Commodore VX automatic 3.8 litre. It runs rough in morning for about 8 minutes then it's good. What could be wrong with it ? Thank you.

No references to this vehicle at all-suggest you check fuel pressure and the idle speed controller

Check fuel pressure and replace the fuel filter if it is looking rather old, how long have the plugs been in? get the coil pack Cva readings checked, you may have low voltage on one coil in the pack, and a scan will also help, as not all fault codes will set a check light.
