Additionally, a cat failure is typically the result of a engine related issue that has destroyed or reduced cat efficiency over a period of time. (If air can't get out the rear of the vehicle, it can't come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture. When hot exhaust gases are forced through the catalytic converter, they contact the catalyst substrate. If it is the one before the CAT, then the sensor can just be bad. Fuel and engine additives can cause converter failure, some of these additives are not oxygen-sensor safe. Hiighly unlikley that something could be sucked backward into the engine, cat can cause excessive backpressure but the flow is still out the exhaust, not backward into the engine.

A clogged catalytic convertor causes the symptoms of a loss of power when accelerating or going up a hill. Not only will you end up with smoke belching Chevy, the lead can also cause the converter to overheat and catch fire. Excessive unburnt fuel in the exhaust can cause the catalyst to reach extremely high temperatures which can cause damage to the fine catalyst material. In this instance, unburned fuel will enter the catalytic converter and very likely ignite on the element (the heat shield that surrounds a "cat" is there for a reason), damaging the converter and making it perish faster.
