did they do a comression test? perhaps you should. one and two misfiring? they are on the same coil pack? maybe wires were switched by mistake?
Well I did the work myself I had to replace 2 coil packs which are on 2 and 4 cylinders and the wires are right and 1 and 2 aren't on the same coil I disconnectedthe battery to reset the computer and took it up to the auto parts store and the same codes are showing with the new coil pack and all new spark plugs Ngk iridium plugs .

these things are bitches to work on. never did get around to that compression test?, anyways, if it was running rough prior to your corrective surgery, it could be serious. dry compression test would tell us if this is in fact an electrical goblin-
Did the compression test on 1&2 cylinders and there is no compression and the number 2 cylinder spark plug had oil on the tip what could be the possible problem please help the other cylinders were fine .
