More than likely the catalitic converter is stoped up. It is flanged so you can remove it and knock the insides out with a large screwdriver or piece of pipe; untill you can make a permanent repair with a replacement. They run about $150.00on ebay.

Sounds like you have a bad coil. The cylinders that are not firing are dumping raw fuel into your cats. Will not idle because its misfiring. Had the same problem on a SC400.
