I have a miss in #4 cyl. at idle its ok. when you raise the idle a little the spark to # 4 cyl stops. No spark at wire. It has new plugs,cap rotor,and wires

You may have a faulty ignition module. since everything else seems to be taken care off. and since you say spark stops it wouldnt be an injector.
