Diagnostics states #3 injector not starts rough and after it gets above 40mph it smoothes out . wires &plugs, coil pack,#3injector , plantium gasket all changed! We are stumped!!! ?...

what you have to do is connect a noid light on the #3 injector and see if it is wirking, if not there is a broken wire or the drive for that injector in the ecu is bad, which means you need to replace the ecu
