Guys I have a 99 Malibu with a 2.4 engine.This car has a 135k on it and has been a great car for us. Several days ago the car starting running awful as it would stall and hesitate very badly. It seems to be okay when you're on the highway but when you get in stop and go traffic it runs bad. I thought maybe we got some bad gas or water in the gas tank so I added some dry gas and fuel system cleaner but that hasn't helped. Today I cleaned the throttle body and although I put a smoke show on for the neighbors it didn't solve my problem. When it sits and idles it sounds like a slow chugging noise is coming from right under the passenger compartment and I noticed kind of a putt putt coming from the exhaust pipe.Could I have a clogged catalytic converter and how can I check.Also any other suggestions on what the problem might be are greatly appreciated.

Guys I forgot to mention that when I was checking out the exhaust coming from the car I looked under it and even though it was idling badly and sounded like it would stall,it seemed like the whole exhaust was shaking or vibrating an awful lot.Don't know if that means anything or not.
