Their MURDERED!

Catalytic converters stop functioning because they have either fallen asleep (sooted up – like a chimney) or they have been murdered (over-fueled and burned out). Seldom do they ever die of old age. This catalytic converter began melting down because sensors drifted and fuel trims shifted. A computer will do just about anything to make the engine run great but it is still your responsibility to maintain your vehicle.

Remember, “An ounce of prevention is worth a pound of cure.” Translation, “A little maintenance today prevents major repair bills tomorrow.”
