What happens if you drive with a bad catalytic converter?
If you drive with a bad catalytic converter, your car’s emissions of harmful pollutants may increase significantly.
The catalytic converter is an important component in your car’s exhaust system.
It converts harmful gases like carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances before they are released into the air.
When a catalytic converter is damaged or not functioning properly, it may not be able to effectively filter out these harmful pollutants.
This can lead to increased emissions. This not only harm the environment, but can also cause your car to fail an emissions test or even lead to a ticket or fine.
Moreover, a bad catalytic converter can cause your car to run poorly, with symptoms like reduced power, decreased fuel efficiency, and a rough idle.
So it’s important to address any issues with your catalytic converter as soon as possible.
