Best Answer

you will smell rotten eggs all the time when u r driving around

You will get a "check engine" light. On 1996 and newer cars there is a plug near the drivers seat you can plug a cheap device into and it will tell you what "codes" the computer is giving. Google "car chip" Very interesting gizmo


If the cat is way far gone the engine will run poorly. Stalling, sputtering, hard starts, not start at all, backfire. You may actually not even get a code other than misfire or knock sensor which are symptomatic not fundamental to the problem.

If a cat has failed it needs replaced. There is no repairing a cat.
