The check engine light came on, autozone put the code reader on it, the code came back cylinder 3 misfire. I changed plugs, reset light (by disconnecting battery for a minute or so) hooked up code reader and still read same. Changed wires, reset battery, still same misfire. So, then I switched ignition coils... I put cylinder 3 coil on #2 cylinder, to see if number two cylinder would misfire.... After the reset, put the code reader on it and now it reads cylinder 6 misfire.... Help!
