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-
