2012 lpg commodore Omega CD series ii MY12
Hi I am having an engine misfire for the past 3 months. I have got the spark plugs coils and manifold gasket replaced. But the problem is still there. I have tried 3 different types of coils but each time I replace them the car seems to work fine for about 2 weeks but after that all of sudden while driving the car will have serious misfires and traction control sensor errors start coming up. It’s weird I am not sure what to get fixed next. Please help I can’t afford to stay of the road for too long and can’t afford a new car.

Thanks for your reply. One of the mechanics said the error code is PO300. Which means all sorts of errors can be present I think. Would you suggest taking to Holden dealer (will that cost too much ) or could you suggest another mechanic or another option, I live in Parramatta Sydney.

VZ Crewman, VZ Cross 8, & ya mum.
Can be crank reluctor ring damage.
Blocked or damaged cat/cats (can be partly tested with an infra red thermometer)
Faulty coil/s (can happen with new ones too)
Can be worn accessories on the front of the motor creating excessive vibration.
Can be vacuum leaks.
Faulty plug (Can happen with new ones)

Someone else might be able to add more to this?

So I think maybe I should get this car scanned by someone more professional and specialised in Holden Commodores. Thanks for your help
