Hi I'm just wondering what would make my commodore misfire I've changed all 3 coil packs and plugs, leads,oil, oil filter, air filter, fuel filter and it is still missing could it be the DFI MODULE it does it on idle and gets worse under load. Now it's showing the check engine warning message on the instrument panel

Get it scanned to see what Code is causing the DTC to activate,
Then take it from there.
