    VZ Commodore powertrain problem

    Holden Holden Advice Holden Commodore Holden Commodore Advice Holden Commodore 2005
    ...
    A few weeks after buying my VZ Holden Commodore wagon the powertrain warning light came on. My mechanic diagnosed the problem as faulty oxygen sensors and replaced them. The car ran without a problem for two months before the warning light came on again, this time a catalytic converter was replaced. The warning light has come on yet again. Can you advise what is causing the problem?

    It's not possible to diagnose your problem with any certainty, the mechanic is obviously checking the things that do go wrong, but hasn't clicked on the right thing yet. I would have the crank angle sensor checked.
