Straight intake causes a rough takeoff

I took out the resonator and the MAF tube and replaced it in that little corner with a straight pipe and a cone air filter. I cut a rectangular hole in the piping for the MAF and sealed it in pointing the right direction.

Initially I had the check engine light but I was told I should disconnect the battery to reset the emissions settings. That fixed the light (I drove around for about ten minutes and it didn't come back on), and it seems to have power still, though I'm not sure if it's the same amount or more or less.

Anyways the problem I'm seeing now is that from a takeoff if I go slow like you normally would just driving around at about 2000 RPM it jerks a bit like it's starving for air or something. Could this be as a result of the filter?

Give me until tomorrow and I can post pics.
