    missfire from 1 to multiple

    I just put on pacestter headers and full three inch exhaust with slp loudmouth and cacto cat. after I it all done I scanned it and I got a missfire on cyl 3 so I searched and everyone said change the plugs and wires. The previous wires were only ten thousand miles old but I thought they might have burnt since the new headers. So got all new wires and plugs replaced the old and now I am getting multiple misfire codes and it is running like ***t. The wires are just autozone duralast and the plugs are NGK-TR55IX.
    Thanks for your help

    maybe a coil, I have had a similar problem and the missfire were caused by 2 ignition coils out.

              what you 2 just said is exactly what happened to me. started out mis-firing from cylinder 3 the computer at auto zone said, then got a tune up wires and all then changed 2 coil packs and it's running great. one suggestion, don't have big hands and try to change coil packs.
