A clogged catalytic converter translates into a lower engine power, irregular running of the engine and vibrations in idle run. Do such symptoms always indicate the necessity to replace the converter? How can you pay less for the repair? Can a catalytic converter be unclogged by running the engine at high RPM and, hence, avoid the purchase of a new one?
A catalytic converter is an essential part of the exhaust system. With its honeycomb structure coated with catalysts which accelerate the reactions inside the converter the catalytic converters improve the quality of the exhaust gas with a positive effect on the environment. Currently, the catalytic converters are installed both in petrol- and diesel engine driven cars with an aim of reducing air pollution.
Catalytic converters, just like all other parts, can be mechanically damaged or simply get worn out with time. Replacement of a catalytic converter means high costs of the converter itself and those to be paid for the service of a specialist who will do the repair. What are the symptoms of problems with the catalytic converter? First of all, low engine power, irregular running of the engine and vibrations in idle run. In many cases these are the symptoms of the converter being clogged. It is often said that a clogged catalytic converter can be unclogged by running the engine at high RPM. Is it really possible? And to what extent is such a solution safe?
Unclogging a catalytic converter using “amateur” methods is not possible. A catalytic converter with a ceramic or metal core is an extremely fine component. Therefore, driving your car with the engine running at high RPM while the catalytic converter is clogged, which is theoretically recommended in such a case, not only will not help but, on the contrary, it will accelerate the degradation process. Therefore, if you ask how to unclog a catalytic converter by running the engine at high RPM the answer is: Do not even try doing that. Unfortunately, a replacement of the damaged part will be necessary.
To reduce the price of the repair we recommend to sell the old, worn out catalytic converter at a collection point. By doing this you will at least partially recover the money spent for the replacement. We do not recommend to buy all-purpose catalytic converters as they may prove unsuitable for your car.
