have it scoped to test plg wires.find a shop that will fix the car,sounds like a plug wire is breaking down

Was your code something like a po303, showing that it was a misfire in Cylinder number 3 ? If so and you changed the plugs already, you can check the coil real quick. Switch it with the coil from another cylinder then scan for codes again. If the code changes to a misfire in the cylinder you put the coil from number three in, the coil is bad replace it. If the code dosen't change you may have a bad injector.
