Dont know what happening. driving normally, then stopped at the lights. all of a sudden, engine just started to rev and constantly stayed revving - in neutral, and even in gear if the car is stationary. revving to 2half 3 bar.

having a look at the engine bay, all hoses are connected, no holes in the air induction pipes....

car is stock except for K&N pod filter.....

Please please anyone know what the problem is....
