Did you know that your vehicle’s catalytic converter plays a crucial role in converting unburned fuel and nitrogen oxide into less harmful substances? It then releases safer emissions through the exhaust. When the converter malfunctions, it can significantly affect your vehicle’s gas mileage and performance. Below are ways to tell when you need car maintenance and a new converter installed to ensure your vehicle performs optimally.
Illuminated Check Engine Light
If your car’s converter malfunctions, the oxygen sensors in your vehicle will detect that the exhaust gases are not adequately catalyzed. This will cause the check engine light on your dashboard to go on. Call us as soon as possible when you see the check engine light is on to prevent further damage to your vehicle.
Sulfurous Odor
During the combustion process, the sulfur present in the fuel transforms into hydrogen sulfide. The converter then converts the hydrogen sulfide into sulfur dioxide, an odorless gas. When the converter fails to do its job correctly, it won’t convert all the gas, resulting in the emission of an unpleasant sulfurous odor from the exhaust similar to the smell of rotten eggs.
Poor Acceleration
A converter is a metal container between the exhaust manifold and the muffler. The converter contains a honeycomb mesh. Over time, the mesh can get clogged with carbon buildup. It can also get damaged when the heat from unburned fuel melts it. When there is a blockage, it will restrict the exhaust flow, making your car feel slow and sluggish when you step on the gas pedal.
Increased Fuel Consumption
When the converter is not working correctly, you may notice that your car is consuming more gas than usual. The problem could be an obstruction due to blockage preventing exhaust flow, causing you to stop at the gas station to fill up more often.
Rattling Noises
Over time, the mesh inside the converter’s container begins to deteriorate due to excessive heat or damage. When the mesh breaks down, it will start to make noises. You will hear rattling when driving, especially when your car idles.
Stalls and Hard Starts
If you hear rattling noises from under your car, and the converter causes it, replacing it as soon as possible is best. When the mesh inside the converter breaks up, it can make its way into the muffler and cause severe damage. Once the material enters the muffler, you may struggle with stalling and difficulty starting your car.
Typically, a converter’s lifespan is around 100,000 miles or a decade. A malfunctioning converter can cause frustrating car problems. However, if you notice symptoms of a faulty converter, there’s no need to worry. Call Rath Auto Resources Fort Smith now to schedule an expert replacement and make all your vehicle problems a thing of the past.
