Default missfire at only 2000 rpm then its fine? Help?

Alright so i have a 92 civic dx with a d16y7 engine swap, and for some reason it like missfires between 1700-2000 rpm and i cant figure out why. I put new plugs and wires in it seemd to help a little but the problem just came right back. next thing im thinking about is maybe my coil pack? any other suggestions on what it could be?
Thanks for any help!

There's a sticky at the top of this section on how to check CELs. Use that.
