Help!

I've got a DCT 3ml with a single coil carto in it. I've filled up my juice and put it on a 900mah ego battery and lavatube but the draw is really airy! Like there's too much air going into it which isn't very satisfying at all!

Can anyone help me with this?

I have a similar set up, when this has happened to me it has been down to a drop in voltage!

Would duel coils be better then singles for the standard battery?
