You mean 304. See my response to other poster. Before changing the wire just twist the coil end #4 wire so it doesn't touch metal, and make sure the plug end boot is PUSHE ON securely. Clear CEL. It it recurs check plug. If wet or bad replace; if wet use stop-leak in oil to close up oil leak. Very rarely will a coil pack be bad.
