Hi all, Recently after driving my aurion slightly harder than i usually do, when stopped at the lights my engine seemed to increase in idle several times whilst i was still stopped (like i was reving it) . Also after take off the gearing was very sharp and jerky. Just wondering what this could have been from? Excessive fuel intake? Poor fuel? Computer not recognising the fuel it used and a slightly light mix being used? dirty throttle body? Im not too concerned, as it stopped fairly quickly just wondering what would cause this? or the most common cause? Cheers
