Airbox - What gives?

Well, the guy who owned my 325i (1989) had a cone filter installed. I changed it back today, to the stock airbox. It now seems that whenever I try accelerate, the engine doesnt get enough air. When I stand over the engine, and rev the it, it sounds as if there is an instant vacuum and then it breathes properly again. I dont have the acceleration or power because of this.
Do I have to change anything on the airbox or the airflow meter? If so - How?

What gives is that you just reduced your engine's air supply. There's a reason that people put in cone filters. If you want the extra power, put the cone filter back in.

Rip it all back apart again and make sure that there isn't anything that shouldn't be there.

Its not a question of not having the power I desire, its a question of not having any power at all, as if I've just bunged up the air intake with a cloth....... BUT....... guess what stupid me didnt do - I forgot to connect the AFM wire back to the AFM - Hence the loud vacuum sound and lack (NO) power.
