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.
