Symptoms of a Bad Catalytic Converter

By now, you've probably heard of the catalytic converter. But what exactly is it, and what does it do? The catalytic converter is a vehicle emission control device that converts exhaust fumes into less toxic gases. But what happens when this essential component isn't working correctly? A faulty or bad catalytic converter can cause all sorts of problems for your car.
This blog post will discuss a few telltale symptoms of a bad or faulty catalytic converter.

Check Engine Light is on

One of the most elemental signs that your catalytic converter might go bad is if the "check engine" light comes on. This check engine illumination could indicate that the converter is not functioning correctly and needs replacement.
Suppose the oxygen sensors in your car detect that the exhaust fumes conversion is wrong; it will trigger the check engine light.

Car Engine Suffers Poor Performance

During startup, it's likely to hear the engine stalling or sputtering. A bad converter leaves the car with a hard time starting due to the build-up of unburned fuel in the exhaust system.
A faulty catalytic converter can also cause engine performance issues while driving. If you notice your car losing power or having trouble accelerating, it could signify that the converter needs replacing by an auto repair shop.

Sulfur Smell From Exhaust

Another symptom is the smell of sulfur coming from the exhaust. Sulfur dioxide is one of the gases that the catalytic converter should convert.
If you can smell sulfur, the converter isn't doing its job correctly and needs to be fixed or replaced.
Bad catalytic converters often have a rotten egg smell due to the high levels of sulfur in the exhaust fumes.

Increased fuel consumption

Have you noticed a drop in your gas mileage or your car's fuel tank emptying more quickly than usual?
When the converter isn't functioning systematically, the engine runs richer because unburned fuel releases into the exhaust system.
