Most likely cause spark plug wire bad, or you got them incorect when you did a tune up if it happened before tune up. swap the wires but keep the fire order the same . if the wires are good then the # 4 should still be the problem . put them back the way they were now you have ruled out the wires next check the fuel injetion system check for a vacum leak around the # 4 injector listen with a lenght of hose . listen to the injectors they should all be making a clicking noise.cant help you more then that. make and model would help the next expert wiz or guru
