My mechanic already did that, and the fault code indicated it was a spark plug. So changed that, and the issue went away for about 2 weeks and then came back. He reckons it might be the injectors, and if so, will need all of them replaced.
Apparently you need all replaced, and each one costs $700 or something ridiculous. I have had the worst luck with this car. Had to pay for both turbos to get replaced at 91 KM's.
