Take it to holden, have them read the fault codes, then repair as necessary, dare say it be your coil packs

i had same issue cpl of months ago. my obd reader was dead so took it to holden and got them to read it. P0300 and P0303 was the codes (misfire and misfire in no.3 cylinder). Not a hard repair. Did it myself. About 2.5hrs if your handy with the tools. I replaced all six and the manifold gasket. Cost me $100 ea for Fuelmiser coil packs from Repco and i think it was about $30 for the gasket (metal with rubber seals as opposed to the fibrous stuff that they use in factory). Someone on here posted the pages from a workshop manual that shows how to change them. If i can find them i will post the link

are you in fairfield brisbane mate? I go past there most days and could help you out

Its rather easy to remove the manifold, then the coil packs are directly below it, just unclip them and swap..
