Default 12v misfiring after DV leak fix?

So i finally got my DV socket, which i ordered to fix the two leaking DVs. Took DVs out and replaced small o-rings, but didnt change the green o-ring. threw everything back together,fired it up and its noticeablly misfiring. I cracked the lines to find out which cyl it was, second one back from front of motor.dissasembled and cleaned the injector to make sure it wasnt grit sucked through from when i opened the DV up. everything back together. Still misfiring.no black smoke at idle, idle drops a little and smooths out when i crack misfiring line. Any ideas? maybe i put something in wrong?
