Hi guys, had a photo shoot tonight in dubbo. and i now have issues where if im doing under say (including being stationary, either in or outof gear!) 5-10km/h the car rev hunts from between 1500-2000rpm, while trying to drive the car will jerk back and forward as it bounces between 1500-2000rpm until speed is picked up! i have not changed anything tonight, i did not wash my engine bay, i have not changed anything. i was not thrashing the car, as we were taking photos and the police were present! i checked my tps and speed sensor and all other sensors where plugged in?

what is going on??
