Sulfur smell means dead cats. They need replacing as does the o2 sensors and MAS sensor. The OEM cats would be prohibitively expensive so try calling a muffler shop to get some new cats. The rough idle could also be coming from a slightly clogged cat. The ignition system helps but the problem is in the fuel injection which is moderated by the 2 o2 sensors and MAS
