IS F 2nd intake flap not opening
Hi
My cars lost its induction noise at 3600 rpm upwards seems the 2nd intake flap is not opening and the vacuume is keeping the flap closed.
With the engine off it opens and with engine on it closes.
Is something not triggering the vacuum to stop so it opens?
Any help appreciated
Thanks
John

17308-38010 covers everything from the manifold to the VSV. Might be a cracked check valve too.
