sounds like you have the firing order off ! re- trace your wires from coil packs to plugs, you have one or several mixed up, the coil packs are numbered, and you wil have 135 on one bank and 246 on the other, If I'm not mistaken 135 are closest to the radiator, you can tell by seeing which head is the farthest forward towards pass side of car and that is Bank 1 which will have 135 cylinders.
