hey guys I have a 2001 vx Commodore auto v6 ecotech, about 3 weeks ago I wash the engine bay out ( I know, dumb idea) and ever since it has been miss firing, I have literally done everything, first I replace leads, plugs which needed to be done anyway, then next new coil packs and dfi module this made it alot better how ever still missing, next emptied fuel tank, filled with no ultimate and injector cleaner, and changed fuel filter, still missing, removed fuel rail and cleaned fuel rail and injectors, starting to get through all the obvious things and getting no where so I went and bought a holden service manual I followed all the troubleshooting for the missing, tried a friends air flow meter, checked egr valve, compression test, spark test, then I thought after the really bad miss firing at the start may have stuffed the o2 sensors so I replaced those, made it slightly better, as you can see I've nearly dome everything I can, I have also had two mechanics look at it and had a scan tool plugged in at Holden, ( no faults) so yeah if any one has any ideas just throw it out there I'm all ears atm cause I don't know what the next step is to fixing the damn thing, NOTE TO EVERYONE BE CAREFUL WHEN YOU WASH YOUR ENGINE BAY OUT!!! haha thanks guys!
