When to fix a bad catalytic converter before replacing it?
The importance here is to always fix these things before you are replacing your catalytic converter. The most common causes of a bad catalytic converter are misfires. So make sure that you have fixed all issues with your engine before replacing the catalytic converter.
Can a bad catalytic converter cause a rattle?
If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle.
How can I tell if my catalytic converter is blocked?
If it comes back slowly or goes low, it means your catalytic converter is blocked. Secondly, the catalytic converter can also be tested manually using IR thermometer. Start the car and let the engine run until it gets fully warm up.
What happens when a catalytic converter is choked?
When your catalytic converter is choked, there almost no working by it. Emissions done by car do not go through catalyst present in the converter and hence converting of high pollutant gases to low pollutant gases is not observed resulting in high emissions.

Can a bad catalytic converter cause an oxygen sensor to go bad?
In 99.5% of the cases, this code means that the catalytic converter itself is bad and must be replaced. However, I see questions all the time on auto forums asking if a new oxygen sensor will fix the problem.
What does a clogged catalytic converter smell like?
Sulfur Smell When catalytic converters clog, they restrict the airflow of exhaust gases so that the engine of your car runs on a rich air-fuel mixture. The combustion of this excessive mixture causes an odor like rotten eggs. This smell smells like burnt sulfur, which is an obvious indication of your catalytic converter’s malfunction.

Can a bad spark plug cause a bad catalytic converter?
An engine that is misfiring because of a bad spark plug, weak coil, dirty fuel injector, leaky valve, or vacuum or EGR leak, may cause the catalytic converter to overheat and suffer damage.
