How do you know when the catalytic converter is giving out on your 2002 Oldsmobile Alero?

1) The exhaust smells like rotten eggs/sulfur...a sure sign.
2) A check engine light. This is because the 2nd O2 sensor (behind the cat) would detect unburned gases in the mixture (ie: the cat isn't getting hot enough).
My 2002 starting running very sluggish. No pep on acceleration. Also overheated. Thought it was the transmission not shifting. No warning lights came on. Got a great mechanic who suspected it, dropped the exhaust pipe and smelled the rotten eggs. If your's goes sluggish, get this checked immediately. You could blow your engine.
