(Bonnet open)
When I quicky "blip" the throttle (dont let it rev)
I hear a noise at rear of inlet manifold that sounds like an open pipe (open induction roar) for a second then it goes away.
Also manifold distorts in ~3 millimeters on the top of rear flat section.
I have looked for loose hoses etc, checked air cleaner and inlet tracts for obstructions etc.
Car still drives well.
It may be normal but I dont have another one to compare too.
