i have change plugs place the wire close a ground source and there is spark to the plug place plug in the wire there is spark at the plug.next had a scanner reading for the injector and at idle was reading numbers not zeroed out like the other injertors were reading.once you start driving the numbers zeroed out replaced number 2 injector and still reading, bad injector on number 2 so i swapped number 3 injector with number 2 injector.scanned again and still number 2 cylinder misfire..
