How can I tell if my catalytic converter is bad?

I feel the truck hesitate when I accelerate, and if I push it, there is a bad smell.

It is bad from what you just described.does it smell like rotten eggs or sulfer like matches?Replace it and it will not only run better but you should get a jump in gas milage.Dont buy the cheap universal ones.If you are keeping the car get a high flow converter.they cost more but are worth it in the long run.
