The cylinders 1,3 and 5 are reading too high, right after a spark plug and wires change, What could it be? I changed the plugs and wires on a 2002 v6 Hyundai sonata due to a rough idle and a loss of power. After the change, it was running GREAT, I drove it for several days with no problem. Four days later after driving all day, it started choking and sputtering and I had a huge loss in power. I took it to the local auto store to check the codes. The Machine read that all cylinders were misfiring and Injectors 1,3 and 5 were reading to high. I'm not sure what to start with, being that it was running fine and all of a sudden it happens. Any ideas and expertise would be greatly appreciated. Thanks
