If you think you have a failing catalytic converter it is advisable to take your vehicle to a mechanic and have them diagnose the issue. A catalytic converter is a vital component of the vehicle’s exhaust system that works to convert harmful gases into safe compounds that can be passed into the atmosphere and cause less damage to the environment. This part is found between the engine and the exhaust muffler on the underside of the car. It is not uncommon for a catalytic converter to fail, since they are usually more subject to external damage like an impact from debris or internal engine damage brought about by overheating. Below are signs of its failing
Misfiring in the car engine system can cause the catalytic converter to overheat. Additionally, an exceptionally rich fuel mixture will show similar symptoms. When there is a presence of an extra rich fuel mixture, raw fuel enters the catalytic converter and is ignited. The catalyst parts can melt under such conditions.
2. REDUCED PERFORMANCE
If exhaust becomes trapped in front of the catalytic converter, there will be a latent reduction in engine performance. This is caused by back pressure, which affects the running of your engine and prevent it from breathing. The sudden increase in back pressure can make your engine to stall during your drive. It will act as though there is an air lock in your system, making the car jerk or feel like there is no fuel getting to the engine when you push the accelerator.
3.REDUCED FUEL ECONOMY
A failing converter can make a noticeable decrease in your fuel economy, which will cost you significantly over a very short period of time.
4. LOW PERFORMANCE OF THE EXHAUST SYSTEM
The cause of a failing catalytic converter can sometimes be investigated back to an error in the fuel system. A distinctive sign of this is a restriction in the performance of the exhaust system, showing the melting of catalyst materials inside.
5. FUEL VAPOR
If your car is equipped with a carburetor and you know how to test the catalytic converter, then do it. Remove the air cleaner and enlist the help of a friend. They will need to hold a strong light near the carburetor intake. Glance over the top of the carburetor toward where the light is shining and rev the engine. If you see signs of fuel vapor suspended over the carburetor, you will be able to safely deduce that there is a clog in the catalytic converter.
Another way of identifying whether a catalytic converter is failing is to temporarily take out the oxygen sensors from the exhaust. If there is an obvious alteration in the performance of the car then you can be sure the converter has a clog and is going bad.
7. INCREASED EMISSIONS
Contamination of the chemical mechanisms inside the catalytic converter, created by the addition of substances such as motor oil or antifreeze, can stop it from performing correctly. If this is happening, you will see a raised level of carbon emissions coming from your exhaust. You will need to change the failing converter and fix the source of this problem before it does damage to your entire exhaust system or emits an illegal amount of emissions into the atmosphere.
