Best Answer: When a catalytic converter goes bad it will restrict the flow of exhaust gases through the exhaust system. Basically, if the exhaust won't come out easily, air won't be taken into the engine easily to mix with the fuel to be burnt and give you power.
This is usually a sign that the catalyst has become plugged. It may be caused by faulty sparkplugs or an exhaust valve that has been burned. The catalytic converter can plug up and cause those symptoms. The converter can be tested by doing a back pressure test.If the converter is totally plugged it will get almost red after driving a while (very hot). Also exhaust will be restricted out of the tail pipe.logged Catalytic Converter Symptoms 101 Clogged Catalytic Converter In Your Car Understanding Of Symptoms Of Bad Catalytic Converter Bad Catalytic Converter In Your Car.
