My car 2004 1.6 gasoline 307

When I step on the gas regardless of the gear, when the speed approaches 30a and passes, there is a drowning noise from the engine .

The filter box may have been removed. Check the air hoses.

I opened it and checked it, but it looks like there is no problem with the filter and hose. The air filter had just changed. Is the air filter of the 307 soft?

Not the filter, the filter box itself is not properly installed. Also check part 7 for any broken holes.

See the figure.

Now I had a sole sound, I even shared it in the forum, but I couldn't find a solution. The sound sole was gutted in other gears, an extra sound that grew up in 1st gear, was grumbling in the vehicle, sometimes it was in other gears. We heard that the vehicle was lifted in the fiber. After the manifold, there was a part of the catalyst, the wire wrapped with the wire, you see, when you lift the vehicle, it looked like I missed it.
