Скачать или смотреть What Makes A Catalytic Converter Go Bad

Having trouble with your catalytic converter? There are lots of reasons these vital emissions parts fail: from contamination by oil or coolant, to raw fuel in the exhaust, overheating, physical damage, and even sensor issues. Modern cars are sensitive—if your engine runs rough or you ignore that check engine light, you could be on the fast track to converter failure. Even short trips or using cheap gas can build up damaging residue. Over time, age plays a role too—after 100,000 miles, most converters are living on borrowed time.

Want to avoid an expensive repair? Give your engine (and converter) regular maintenance: keep sensors, spark plugs, and fuel systems healthy, and always check the exhaust when you fix other engine issues. A little prevention goes a long way—don’t let your converter become an expensive paperweight!
