GUYS,

i have to tell you your incorrect!!

I had this issue twice but not to the extent satch has. I threw mine into neutral expecting it to rev straight up to the limiter but it didnt. The minute i threw it in neutral the revs died back down. My initial thought was the throttle suddenly jamed open but as i said it died back down in neutral. Thankfully i didnt hit the car infront of me i jammed my foot harder on the brake and grabed the gear lever.

Soon as i put it back in gear it was fine.

it has done it twice now and it was just gentle the second time. No idea what it is though, i know the engine compensates when the fan comes on or the aircon kicks in and wonder if that was the sudden increase in revs?

I tend to put it in neutral when i stop now anyway and havent had the problem since.

it never reves without imput when its in nuetral so cant be anything to do with idle control valve etc so it must be an auxillary thats taxing the engine and the engine imediately tries to compensate by increasing the revs?

Anyone got any ideas??
