Often when the converter is plugging, it will glow red hot with the engine running. Other than that, you need to check back pressure at the O2 sensor port.

There is no specific pressure. You are checking to see if pressure is able to exit the exhaust. Therefore, pressure is low if the converter isn't plugged.

If you are getting a sulfur smell, chances are it is the converter.
